Results from a random-effects meta-analysis of the association between the PROCR rs867186 polymorphism and MI (per-allele model). Individual studies are identified by the lead author's last name, year of publication, study name (if a publication included more than 1 study), and reference number. The sample sizes are represented by the size of the squares. Bars indicate 95% CI. Allele frequencies were not reported in the IBC 50K CAD Consortium article.
