MMRMG01

Plots for Mixed-Effect Model Repeated Measures Analysis

Given an MMRM fitted with s_mmrm, g_mmrm_lsmeans displays for each visit the adjusted means within group and/or difference in adjusted means between groups. g_mmrm_diagnostic displays marginal residual plots for evaluating model fit.

Least Squares Means:
Estimates Within Groups

Considering the treatment variable in the model

Code
plot <- g_mmrm_lsmeans(
  mmrm_results,
  select = "estimates",
  xlab = "Visit"
)
plot

Considering the treatment variable in the model, with lines

Code
plot <- g_mmrm_lsmeans(
  mmrm_results,
  select = "estimates",
  xlab = "Visit",
  show_lines = TRUE
)
plot

Considering the treatment variable in the model, with statistics table

Code
plot <- g_mmrm_lsmeans(
  mmrm_results,
  select = "estimates",
  xlab = "Visit",
  table_stats = c("n", "estimate", "se", "ci"),
  table_font_size = 4,
  table_rel_height = 0.6
)
plot

Least Squares Means:
Contrasts Between Groups

Users can choose to display both estimates and contrasts together by running g_mmrm_lsmeans(mmrm_results).

Code
plot <- g_mmrm_lsmeans(
  mmrm_results,
  select = "contrasts",
  titles = c(contrasts = "Contrasts of FKSI-FWB means"),
  xlab = "Visit"
)
Coordinate system already present. Adding new coordinate system, which will
replace the existing one.
