Table 5 Comparison of the cardiometabolic risk outcome variables across 0 and 6 months between the study subjects in the control and low glycemic index, GI, group after adjustment for age, sex and physical activity level

From: A randomized controlled trial to investigate the impact of a low glycemic index (GI) diet on body mass index in obese adolescents

  1. Those outcomes marked with were log-transformed before being subjected to analysis.
  2. Only the model estimates of the regression coefficient (B) of the dummy variables for the group [Group: 0 = Control (reference); 1 = Low GI], time (Month 6 and month 0 as reference), time and group interaction terms (Group*Time) were shown for the mixed effects models with adjustment for age, sex and physical activity level.
