In chevron: Standard TLGs for Clinical Trials Reporting

FSTG02 Subgroup Analysis of Survival Duration.

Description

The template produces the subgroup analysis of survival duration graphic.

Usage

fstg02_main(
  adam_db,
  dataset = "adtte",
  arm_var = "ARM",
  subgroups = c("SEX", "AGEGR1", "RACE"),
  strata_var = NULL,
  stat_var = c("n_tot", "n", "median", "hr", "ci"),
  ...
)

fstg02_pre(adam_db, ...)

fstg02

Arguments

adam_db	(list of data.frames) object containing the ADaM datasets
dataset	(string) the name of a table in the adam_db object.
arm_var	(string) the arm variable name used for group splitting.
subgroups	(character) the subgroups variable name to list baseline risk factors.
strata_var	(character) required if stratified analysis is performed.
stat_var	(character) the names of statistics to be reported in tabulate_survival_subgroups.
...	Further arguments passed to g_forest and extract_rsp_subgroups (a wrapper for h_odds_ratio_subgroups_df and h_proportion_subgroups_df). For details, see the documentation in tern. Commonly used arguments include gp, col_symbol_size, col, vline, groups_lists, conf_level, method, label_all, etc.

Format

An object of class chevron_g of length 1.

Details

• No overall value.

• Keep zero count rows by default.

Value

the main function returns a gTree object.

a gTree object.

the preprocessing function returns a list of data.frame.

Functions

• fstg02_main(): Main TLG Function

• fstg02_pre(): Preprocessing

Note

• adam_db object must contain the table specified by dataset with "PARAMCD", "ARM", "AVAL", "AVALU", "CNSR", and the columns specified by subgroups which is denoted as c("SEX", "AGEGR1", "RACE") by default.

• If the plot is too large to be rendered in the output, please refer to FSTG01.

Examples

library(dplyr)
library(dunlin)

proc_data <- log_filter(
  syn_data,
  PARAMCD == "OS" & ARM %in% c("A: Drug X", "B: Placebo"), "adtte"
)
run(fstg02, proc_data,
  subgroups = c("SEX", "AGEGR1", "RACE"),
  conf_level = 0.90, dataset = "adtte"
)
