Relationship between Angiotensin-Converting Enzyme Insertion/Deletion Polymorphism and the Risk of COVID-19: A Meta-Analysis

Figure 2

Forest plot for meta-analysis of the association between the ACE I/D polymorphism and COVID-19 risk using D vs. I. The solid diamonds and horizontal lines correspond to the study-specific ORs and 95% CIs. The gray areas reflect the study-specific weight. The hollow diamonds represent the pooled ORs and 95% CIs of the overall population. The vertical solid lines show the OR of 1, and the vertical dashed lines indicate the corresponding pooled OR.
