Package 'patientProfilesVis'

Title: Visualization of Patient Profiles
Description: Creation of patient profile visualizations for exploration, diagnostic or monitoring purposes during a clinical trial. These static visualizations display a patient-specific overview of the evolution during the trial time frame of parameters of interest (as laboratory, ECG, vital signs), presence of adverse events, exposure to a treatment; associated with metadata patient information, as demography, concomitant medication. The visualizations can be tailored for specific domain(s) or endpoint(s) of interest. Visualizations are exported into patient profile report(s) or can be embedded in custom report(s).

Description

By default all subjects available in at least one module of listPlots are considered. If only a set of subjects are of interest, these are specified either:

  • directly with the subject IDs of interest via subjectSubset

  • by extracting subjects with a specific value (subjectSubsetValue) in a variable (subjectSubsetVar) in a specific dataset subjectSubsetData

Usage

createSubjectProfileReport(
  listPlots,

If not specified, these are set to the time limits specified when creating each module (stored in attributes(x)$metaData$timeLim) otherwise to the range defined by timeAlign and timeAlignPerSubject. Note that this doesn't modify the geoms of the plots, it only extends the axis range. So for interval module(s) if the specified timeLim is smaller than the time limits in the input plot, no arrows are created in case than the time goes above/below specified timeLim (the segment is cut).
timeAlign

timeAlignPerSubject

Character vector, specifying if the plots should be aligned (or not) across subjects

  • 'none' (by default): all modules to align have the same time limit across subjects

  • 'all': all modules to align have different time limits per subject

  • character vector with subset of the modules to align per subject (should correspond to the names of listPlots)

Only the modules already specified in timeAlign can be aligned by subject.
refLines

(optional) nested list with details for reference line(s). Each sublist contains:

reportPerSubject

Logical, if TRUE (FALSE by default) export a subject profile report by subject.
exportBatchSize

(optional) Integer, if specified, the patient-profile reports are created by batch of this number of subjects. This might speed up the export for a high number of subjects. Only available if report is created by subject (reportPerSubject is TRUE) and modules are not aligned across subjects (timeAlignPerSubject is: 'all').
labelVars

Named character vector with variable labels (names are the variable code)
maxNLines

Maximum number of lines for a combined plot, to fit in the page height.
When the different visualizations are combined for each subject, they will be allocated to different pages if the number of lines of the combined visualization is higher than this number.

  • 'caption': String with extra explanation concerning imputation that could be included in plot caption.

Time interval representation

In case the start or the end of the time interval contain missing values:

  • if a dataset (timeLimData), start (timeLimStartVar) and end (timeLimEndVar) variables are specified:

    1. for each subject:

      • the minimum and maximum time values across these specified time variables are extracted

      • missing start values are replaced by the minimum time

      • missing start values are replaced by the maximum time

    2. if all values are missing for this subject, they are taken across subjects

  • otherwise, depending on the imputation type (timeImpType):

    • 'minimal' (by default):

      • if the start and the end of the interval are missing: no imputation is done, only the label is displayed

      • if the start time is missing and the end time is not missing: start time is imputed with end time, and status is set to 'Missing start'

      • if the end time is missing and the start time is not missing: end time is imputed with start time, and status is set to 'Missing end'

    • 'data-based' (default in version < 1.0.0): minimum/maximum values in the start/end time variables in the data are considered for the specific subject (if available). If there are missing for a specific subject, they are taken across subjects. If all time are missings, the range is set to 0 and Inf

    • 'none': no imputation is done

The symbols displayed at the start and end of the interval are:

  • by default:

    • a filled square labelled 'Complete' if the time is not missing

    • a filled left-directed arrow in case of missing start time

    • a filled right-directed arrow in case of missing end time

  • if the variable(s) used for the shape of the start or end of the interval are specified (via timeStartShapeVar/timeEndShapeVar): labels are based on these variables, and a standard shape palette is used

The time limits are the same across subjects, and set to:

  • timeLim if specified

  • maximum time range in timeLimStartVar and timeLimEndVar in timeLimData if specified

  • the maximum range on the data obtained after imputation of missing values

list with parameters used to specify the format of the report, e.g. output of the subjectProfileReportFormat function
paging

Logical, if TRUE (by default), automatic paging is enabled, so patient profiles module too big to fit in one page will span multiple pages. Please note that the size of the graphic window (or report page) may need to be re-sized in order that the plot fits.

Value

list of (across subjects) of list (across pages) of ggplot2 objects, also of class subjectProfileIntervalPlot. with additional 'metaData' attributes containing 'label', 'timeLim' timeTrans and timeExpand (if specified).

Time interval representation

In case the start or the end of the time interval contain missing values:

  • if a dataset (timeLimData), start (timeLimStartVar) and end (timeLimEndVar) variables are specified:

    1. for each subject:

      • the minimum and maximum time values across these specified time variables are extracted

      • missing start values are replaced by the minimum time

      • missing start values are replaced by the maximum time

    2. if all values are missing for this subject, they are taken across subjects

  • otherwise, depending on the imputation type (timeImpType):

    • 'minimal' (by default):

      • if the start and the end of the interval are missing: no imputation is done, only the label is displayed

      • if the start time is missing and the end time is not missing: start time is imputed with end time, and status is set to 'Missing start'

      • if the end time is missing and the start time is not missing: end time is imputed with start time, and status is set to 'Missing end'

    • 'data-based' (default in version < 1.0.0): minimum/maximum values in the start/end time variables in the data are considered for the specific subject (if available). If there are missing for a specific subject, they are taken across subjects. If all time are missings, the range is set to 0 and Inf

    • 'none': no imputation is done

The symbols displayed at the start and end of the interval are:

  • by default:

    • a filled square labelled 'Complete' if the time is not missing

    • a filled left-directed arrow in case of missing start time

    • a filled right-directed arrow in case of missing end time

  • if the variable(s) used for the shape of the start or end of the interval are specified (via timeStartShapeVar/timeEndShapeVar): labels are based on these variables, and a standard shape palette is used

The time limits are the same across subjects, and set to:

  • timeLim if specified

  • maximum time range in timeLimStartVar and timeLimEndVar in timeLimData if specified

  • the maximum range on the data obtained after imputation of missing values

There are two ways to specify the variables of interest to include:

  • by specifying column(s) of interest containing parameter values, passed to the paramValueVar parameter.
    In this case, variable value is displayed in the plot area, and variable name in the label of the y-axis, as:
    variable 1 | value 1 - value 2 - ...
    variable 2 | value 1 - value 2 - ...

  • by specifying column(s) of interest containing parameter values, displayed as a table.
    In this case, variable are displayed in columns in the plot area. Variable names are displayed on top of table, and associated values below, as:

    | value 1 value 1 | ...

  • by specifying a combination of a variable containing the parameter name (paramNameVar), coupled with a variable containing the parameter values (paramValueVar).
    In this case, parameter values (if multiple) are concatenated and displayed in the plot area for each parameter name, displayed in the label of the y-axis, as:
