LBT14 Laboratory Test Results Shift Table – Highest NCI-CTCAE Grade Post-Baseline by Baseline Grade (Low or High Direction).

Description

LBT14 Laboratory Test Results Shift Table – Highest NCI-CTCAE Grade Post-Baseline by Baseline Grade (Low or High Direction).

Usage

lbt14_main(
  adam_db,
  arm_var = "ACTARM",
  lbl_overall = NULL,
  gr_missing = "incl",
  page_var = "PARAMCD",
  ...
)

lbt14_pre(adam_db, gr_missing = "incl", direction = "low", ...)

lbt14_post(tlg, prune_0 = TRUE, ...)

lbt14

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

gr_missing

(string) how missing baseline grades should be handled. Defaults to "incl" to include the "Missing" level. Other options are "excl" to exclude patients with missing baseline grades and "gr_0" to convert missing baseline grades to grade 0.

page_var

(string) variable name prior to which the row split is by page.

...

not used.

direction

(string) one of "high" or "low" indicating which shift direction should be detailed.

tlg

(TableTree, Listing or ggplot) object typically produced by a main function.

prune_0

(flag) remove 0 count rows

Format

An object of class chevron_t of length 1.

Details

• This table follows ADaMIG v1.1.

• Only the worst grade recorded for each patient is included in the table.

• If no missing baseline lab results, the "Missing" level of BTOXGR is excluded.

• Grading takes value from -4 to 4, negative value means the abnormality direction is low, positive value means the abnormality direction is high.

• Grades 0, 1, 2, 3, and 4 are counted as "Not Low" when direction = "low". Conversely, when direction = "high", Grades 0, -1, -2, -3, and -4 are counted as '"Not High".

• Remove zero-count rows unless overridden with prune_0 = FALSE.

• Split columns by arm, typically ACTARM.

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

• lbt14_main(): Main TLG function

• lbt14_pre(): Preprocessing

• lbt14_post(): Postprocessing

Note

• adam_db object must contain an adlb table with columns "USUBJID", "PARAM", "BTOXGR", "ATOXGR", and the column specified by arm_var.
