Generates a table displaying vital signs measurements across multiple visits, showing sample size, mean, and standard deviation by treatment group.

Usage

create_vs_by_visit_table(
  data,
  paramcd = "SYSBP",
  visits = c("Baseline", "Week 2", "Week 4", "Week 8", "End of Treatment"),
  trt_var = "TRT01P",
  title = "Vital Signs by Visit",
  footnotes = character(),
  autofit = TRUE,
  ...
)

Arguments

data: An ADaMData object (with domain "ADVS") or an ADVS data frame. Required columns include: PARAMCD, AVISIT, AVAL, and the treatment variable.
paramcd: Parameter code to analyze (e.g., "SYSBP", "DIABP").
visits: Vector of visits to include in the table (e.g., c("Baseline", "Week 2", "Week 4", "Week 8", "End of Treatment")).
trt_var: Treatment variable name (default: "TRT01P"). Ignored for ADaMData objects which use their own trt_var property.
title: Table title.
footnotes: Character vector of footnotes to append to the table.
autofit: Logical, whether to autofit column widths (default: TRUE).
...: Additional arguments passed to create_clinical_table

Value

A ClinicalTable S7 object with the formatted vital signs by visit table.

  TRT01P = rep(c("Placebo", "Placebo", "Active", "Active"), each = 2),
  PARAMCD = rep("SYSBP", 8),
  AVISIT = c("Baseline", "Week 2", "Baseline", "Week 2",
             "Baseline", "Week 2", "Baseline", "Week 2"),
  AVAL = c(120, 118, 125, 122, 118, 112, 122, 115)
)
