Graphic representation of AEs

Produce a graphic representation of AE, counting AE as bars for each patient, colored by grade. Can be faceted by treatment arm.

Usage

ae_plot_grade(
  df_ae,
  ...,
  df_enrol,
  variant = c("max", "sup", "eq"),
  position = c("dodge", "stack", "fill"),
  type = c("relative", "absolute"),
  arm = NULL,
  grade = "AEGR",
  subjid = "SUBJID",
  total = FALSE
)

Arguments

df_ae

adverse event dataset, one row per AE, containing subjid, soc, and grade.

...

unused

df_enrol

enrollment dataset, one row per patient, containing subjid (and arm if needed). All patients should be in this dataset.

variant

one or several of c("max", "sup", "eq"). max computes the maximum AE grade per patient, sup computes the number of patients having experienced at least one AE of grade higher or equal to X, and eq computes the number of patients having experienced at least one AE of grade equal to X.

position

Position adjustment (cf. ggplot2::geom_col())

type

whether to present patients as proportions (relative) or as counts (absolute)

arm

name of the treatment column in df_enrol. Case-insensitive. Can be set to NULL.

grade

name of the AE grade column in df_ae. Case-insensitive.

subjid

name of the patient ID in both df_ae and df_enrol. Case-insensitive.

total

whether to add a total column for each arm.

Value

a ggplot

Examples

tm = grstat_example()
attach(tm, warn.conflicts=FALSE)
ae_plot_grade(df_ae=ae, df_enrol=enrolres)

ae_plot_grade(df_ae=ae, df_enrol=enrolres, arm="ARM", variant=c("sup", "max"))

ae_plot_grade(df_ae=ae, df_enrol=enrolres, arm="ARM", type="absolute")

ae_plot_grade(df_ae=ae, df_enrol=enrolres, arm="ARM", position="fill")

ae_plot_grade(df_ae=ae, df_enrol=enrolres, arm="ARM", position="stack", type="absolute")
