Pooled risk ratios and 95% confidence intervals (CIs) were calculated using a random-effect, generic inverse variance of DerSimonian and Laird.<h4>Results</h4>Out of 229 potentially relevant articles, ten studies (five retrospective cohort studies and five cross-sectional studies) were identified and included in our data analysis. The overall pooled risk ratio of CAD in patients with AS was 1.41 (95% CI: 1.29-1.54). The pooled risk ratios for cross-sectional and cohort studies were 2.08 (95% CI: 1.28-3.40) and 1.36 (95% CI: 1.31-1.41), respectively. The statistical heterogeneity of this meta-analysis was moderate with an I(2) of 56%.<h4>Conclusions</h4>Our study demonstrated a statistically significant increased CAD risk among patients with AS with 41% excess risk.Meta-analysisankylosing spondylitis (AS)epidemiologyvenous thromboembolismJournal article2023-11-23
