Figure 3. Forest plot of odds ratios (ORs and 95% confidence intervals) of probable PTSD risks associated with four specific WTC exposure types common between the responders and civilians.

Note: Individual ORs from the original studies, summary ORs for the exposure subgroups, and the overall OR were presented. Details of the studies (a–j) and cohort types were shown in Table 1. IDs (1–37) corresponded to individual ORs in Table S1.
