EGT05_QTCAT ECG Actual Values and Changes from Baseline by Visit Table.

The EGT05_QTCAT table summarizes several electrocardiogram parameters and their evolution throughout the study.

Usage

egt05_qtcat_main(
  adam_db,
  arm_var = "ACTARM",
  lbl_overall = NULL,
  summaryvars = c("AVALCAT1", "CHGCAT1"),
  row_split_var = NULL,
  visitvar = "AVISIT",
  page_var = NULL,
  ...
)

egt05_qtcat_pre(adam_db, ...)

egt05_qtcat_post(tlg, prune_0 = TRUE, ...)

egt05_qtcat

Format

An object of class chevron_t of length 1.

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
summaryvars: (character) variables to be analyzed. The label attribute of the corresponding column in adeg table of adam_db is used as name.
row_split_var: (character) additional row split variables.
visitvar: (string) typically "AVISIT" or user-defined visit incorporating "ATPT".
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.
prune_0: (flag) remove 0 count rows

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).

Details

The Value at Visit column, displays the categories of the specific "PARAMCD" value for patients.
The Change from Baseline column, displays the categories of the specific "PARAMCD" value change from baseline for patients.
Remove zero-count rows unless overridden with prune_0 = FALSE.
Split columns by arm, typically "ACTARM".
Does not include a total column by default.
Sorted based on factor level; by chronological time point given by "AVISIT" or user-defined visit incorporating "ATPT". Re-level to customize order.
Please note that it is preferable to convert summaryvars to factor.

Functions

egt05_qtcat_main(): Main TLG function
egt05_qtcat_pre(): Preprocessing
egt05_qtcat_post(): Postprocessing

Note

adam_db object must contain an adeg table with column specified in visitvar. For summaryvars, please make sure AVALCAT1 and CHGCAT1 columns existed in input data sets.
