In chevron: Standard TLGs for Clinical Trials Reporting

LBT04 Laboratory Abnormalities Not Present at Baseline Table.

Description

The LBT04 table provides an overview of laboratory abnormalities not present at baseline.

Usage

lbt04_main(
  adam_db,
  arm_var = "ACTARM",
  lbl_overall = NULL,
  analysis_abn_var = "ANRIND",
  baseline_abn_var = "BNRIND",
  row_split_var = "PARCAT1",
  page_var = tail(row_split_var, 1L),
  ...
)

lbt04_pre(adam_db, ...)

lbt04_post(tlg, ...)

lbt04

Arguments

adam_db	(list of data.frames) object containing the ADaM datasets
arm_var	(string) variable used for column splitting
lbl_overall	(string) label used for overall column, if set to NULL the overall column is omitted
analysis_abn_var	(string) column describing anomaly magnitude
baseline_abn_var	(string) column describing anomaly at baseline.
row_split_var	(character) additional row split variables.
page_var	(string) variable name prior to which the row split is by page.
...	not used.
tlg	(TableTree, Listing or ggplot) object typically produced by a main function.

Format

An object of class chevron_t of length 1.

Details

• Only count LOW or HIGH values.

• Lab test results with missing analysis_abn_var values are excluded.

• Split columns by arm, typically ACTARM.

• Does not include a total column by default.

Value

the main function returns an rtables object.

the preprocessing function returns a list of data.frame.

the postprocessing function returns an rtables object or an ElementaryTable (null report).

Functions

• lbt04_main(): Main TLG function

• lbt04_pre(): Preprocessing

• lbt04_post(): Postprocessing

Note

• adam_db object must contain an adlb table with columns "PARCAT1", "PARCAT2", "PARAM", "ANRIND", and column specified by arm_var.

Examples
