Methods:
We systematically searched MEDLINE and Embase to identify studies investigating non-adherence to anti-diabetic medications published between January 2000 and May 2020. Two authors carried out study selection, screening, and data extraction independently. Cross-sectional studies that had been conducted among individuals with diabetes in LMICs were eligible for the selection process. Critical appraisal of the included studies was carried out using the Newcastle Ottawa Scale. Meta-analysis was carried out using Stata 14.2. Random effects model was used to compute the pooled proportion at 95% confidence interval.
