Meta-analysis of cohort studies investigating the association between CRP and CAC separated by CRP measurement scale. Diamond represents the summary odds ratio (pooled OR) estimate, and its width shows a corresponding 95% CI with random effects estimate. The square’s size and central point reflect the study-specific statistical weight (inverse of the variance), and the point estimate of the OR and horizontal line reflects the corresponding 95% CI of the study. I2 test and Cochran’s Q statistic were used to assess the statistical heterogeneity (P < 0.10) across studies
