↵a Shown are the mean values for the outcome in the CHW group and the non-CHW group. Calculation of the unadjusted mean A1c change was based on an indicator from an ordinary least-squares regression of the outcome, with no other covariates. Calculation of the adjusted A1c change was based on an indicator for the CHW group from an ordinary least-squares regression of the outcome with prespecified covariates. All CIs were calculated with the use of heteroskedasticity-robust standard errors. Prespecified covariates included history of myocardial infarction, history of stroke, physical activity status, smoking status, and hypertension status. All covariates were measured at time of baseline A1c and were extracted from the UNRWA Bethlehem clinic medical records.
