| USAairports [47] | High | High | Low | Low | Low | High |
| SPANDAU [97,109,110] | Low | High | Low | High | Low | High |
| LSAS [42] | High | Unclear | Low | Low | Low | High |
| SNC [72] | Unclear | High | Low | Low | Low | High |
| AWACS-1 [28] | Low | Low | High | High | Low | High |
| AWACS-2 [28] | Unclear | High | Low | Low | Low | High |
| IVEM [124,128,129] | High | High | Low | Low | Low | High |
* In order to score “low”, the study should contain information that can be used to derive effect estimates that are at least adjusted for age, sex, and smoking; † In order to score “low” participants had to be randomly sampled from a known population and the response rate of the study had to be higher than 60%. Studies with a purposeful sample also scored “low”.
