Comparative Longitudinal Research
Comparative longitudinal research tracks two or more distinct groups across multiple time points, enabling researchers to observe how outcomes change over time and whether those trajectories differ between groups. By combining the temporal depth of longitudinal design with the between-group contrast of comparative design, this approach can detect not only whether groups differ at any single moment but also whether they diverge, converge, or evolve at different rates across the observation window.

Curated claims
Claims persisted in the evidence ledger, each with its own assessment.
This view does not invent a claim assessment when the ledger has none.
