Aggregate summary of the comparator treatment (exercise therapy, ET) for the
continuous ML-UMR example; pair with shoulder_ipd. The two arms
are treated as separate single-arm sources to illustrate an unanchored
comparison. Not real patient data.
Format
A data frame with 1 row and 10 columns: study,
treatment, n, outcome summary (y_mean, y_se) and
covariate summaries (age_mean/age_sd, sex_prop (a
proportion), baseline_vas_mean/baseline_vas_sd).
Source
Simulated; see shoulder_ipd for the modeling basis.
