Generalizability Considerations of Intervention Studies
| Characteristic | Considerations |
|---|---|
| Recruitment site | Were participants recruited from a clinic, the general population, an opt-in from mobile network operator service, or a promotional advertisement? |
| Enrollment eligibility | Were inclusion/exclusion criteria generalizable to a larger population (e.g., mobile phone ownership was not required to participate in study)? |
| Equity | Were study findings equal across all subgroups? Did interventions reach marginalized populations? Were there trends in sharing mobile phones across some populations, which could have mediated effects? |
| Follow-up length | At what time point was the efficacy of an intervention assessed? |
| Target denominator | Was the denominator for the target population a known entity? |
