toxSummary {ProAE}

Create patient-level and group-level summary statistics.

Description

Data format should be in 'long' format, where each PRO-CTCAE item is a variable/column.

Usage

toxSummary(
  dsn,
  id_var,
  cycle_var,
  summary_measure,
  baseline_val = NA,
  arm_var = NA
)

Arguments

dsn

A data.frame object with PRO-CTCAE data.

id_var

A character string. Name of ID variable differentiating each PRO-CTCAE survey/participant entered as a quoted string.

cycle_var

A character string. Name of variable differentiating one longitudinal/repeated. PRO-CTCAE survey from another, within an individual ID.

summary_measure

A character string. Type of summary statistic to be used. Please consult current literature for appropriate interpretations of the summary measure selected and suitable analysis procedures for comparing groups. Options include: "max" = Use subjects' maximum score. "max_post_bl" = Use subjects' maximum score post-baseline visit. "bl_adjusted" = Use subjects' baseline adjusted score over the study period. The baseline adjusted score is derived by the following: If the maximum score post-baseline is more severe than the baseline score, then the use maximum score post-baseline is used as the adjusted score. Otherwise, if the maximum score post-baseline is the same or less serve than the baseline score, then zero (0) is used as the adjusted score. "toxicity_idex" = Construct patient-level toxicity index. "AUC_worsening" = Calculate group-level AUC describing

baseline_val

A number indicating the expected baseline cycle/time point.

arm_var

A character string. Name of arm variable differentiating treatment arms or other grouping factor. Required for group-level summary measures.

Value

A data.frame with only the id and PRO-CTCAE variables being summarized. Each subject will now only have 1 observation (PRO-CTCAE variables are now the summary measure value).

Examples

toxSummary(dsn=ProAE::tox_acute,
id_var="id",
cycle_var="Cycle",
baseline_val=1,
summary_measure = "max")
