Figure 1. Comparison of EHR data and trial data estimated mean weight loss and intervention effect, and EHR-estimated long-term durability effects, from the Track Trial.
Panel A shows the estimated mean weight change separately in intervention and control, for the original Track trial data and the EHR data separately, along with the long-term EHR-estimated weight changes. Panel B displays the difference in weight change between intervention and control, estimating using separate mixed effects models for the original trial data (extracted from the Track main results paper) and the EHR data, along with the long-term (18 month) EHR-estimated treatment effect.
