Read it in context

Observational associations cannot prove equal causal effectiveness. Participants already attended mutual aid; SMART's variation across time and geography also limits interpretation.

Research can describe patterns across groups without predicting one person’s experience. Guidance can explain a program without demonstrating its effectiveness. We identify the source type so you can tell those contributions apart.
