Impact of diabetes mellitus on mortality and atrial fibrillation in hypertrophic cardiomyopathy: A systematic review and meta-analysis

Figure 1 PRISMA flow chart. PRISMA flow diagram detailing the study selection process for this systematic review. A total of 1808 records were identified through database searches (PubMed: 596; Google Scholar: 856; EMBASE: 356). After removing 1477 duplicates and 185 records using automation filters, 135 records were screened. Seventy-nine were excluded, and 56 full-text articles were assessed for eligibility. Of these, 42 were excluded due to irrelevant outcomes (n = 22), lack of effect size data (n = 12), or unavailability of full texts (n = 8). Ultimately, 14 studies met the inclusion criteria and were included in the final review.
