In tern: Create Common TLGs Used in Clinical Trials

Control function for risk difference column

Description

Sets a list of parameters to use when generating a risk (proportion) difference column. Used as input to the riskdiff parameter of tabulate_rsp_subgroups() and tabulate_survival_subgroups().

Usage

control_riskdiff(
  arm_x = NULL,
  arm_y = NULL,
  format = "xx.x (xx.x - xx.x)",
  col_label = "Risk Difference (%) (95% CI)",
  pct = TRUE
)

Arguments

arm_x	(string) name of reference arm to use in risk difference calculations.
arm_y	(character) names of one or more arms to compare to reference arm in risk difference calculations. A new column will be added for each value of arm_y.
format	(string or function) the format label (string) or formatting function to apply to the risk difference statistic. See the ⁠3d⁠ string options in formatters::list_valid_format_labels() for possible format strings. Defaults to "xx.x (xx.x - xx.x)".
col_label	(character) labels to use when rendering the risk difference column within the table. If more than one comparison arm is specified in arm_y, default labels will specify which two arms are being compared (reference arm vs. comparison arm).
pct	(flag) whether output should be returned as percentages. Defaults to TRUE.

Value

A list of items with names corresponding to the arguments.
