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.
