Description
A dataset from of trials for reduction of haemoglobin A1c (HbA1c) in patients with type 2 diabetes(Ding and Fu 2013). Data are reported in each study arm as mean change from baseline to follow-up. The dataset includes 4 Randomised-Controlled Trials (RCTs), comparing 4 treatments.
Usage
diabetes
Format
A data frame in long format (one row per arm and study), with 28 rows and 7 variables:
-
studyID
Study identifiers -
treatment
