LBT01
Lab Results and Change from Baseline by Visit Table.
Description
The LBT01
table provides an
overview of the Lab values and its change from baseline of each respective arm
over the course of the trial.
Usage
lbt01_main(
adam_db,
dataset = "adlb",
arm_var = "ACTARM",
lbl_overall = NULL,
row_split_var = NULL,
summaryvars = c("AVAL", "CHG"),
visitvar = "AVISIT",
precision = lab_paramcd_precision(),
page_var = "PARAMCD",
.stats = c("n", "mean_sd", "median", "range"),
skip = list(CHG = "BASELINE"),
...
)
lbt01_pre(adam_db, dataset = "adlb", ...)

Details
The
Analysis Value
column, displays the number of patients, the mean, standard deviation, median and range of the analysis value for each visit.The
Change from Baseline
column, displays the number of patient and the mean, standard deviation, median and range of changes relative to the baseline.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; first by
PARAM
labels in alphabetic order then by chronological time point given byAVISIT
. Re-level to customize order
Value
the main function returns an rtables
object.
the preprocessing function returns a list
of data.frame
.
a named list
with the precision of each lab parameter code (default is 2
).
