However, participants who were food insecure participants made significant improvement in glycemic control over the course of the trial: a 0.38% decrease (P = 0.01) compared with no change (0.01% decrease; P = 0.87) among participants who were food secure.
We also used graphical methods to compare the distributions of HbA1c between intervention and control groups (again, averaged over the trial period).
These cost components form part of the intervention and were not available to the control group.> Over the trial period of 3 months, the expected mean difference in cost from the Monte Carlo simulation in the base-case analysis was £735 (95% Bayesian credible intervals (CI) £221 to £1,271) and the mean difference in QALYs was 0.052 955% CI 0.040 to 0.063).

The Thai programme investigators described how the establishment of the clinical trial support group has allowed them to exercise more control over how trials are monitored.
