We reserve Validated Grades for interventions that are both peer-reviewed and replicated. This is our highest evidentiary grade.
Convincing Grades are for interventions with peer-reviewed evidence. They have yet to face attempted replication. This is our penultimate grade.

Reduces spread of true but deliberately misleading information
Likely Grades are for interventions with preprinted evidence. Preprints are academic manuscripts awaiting formal peer review.
Tentative Grades occur when randomized controls or independence from vested interests are absent. It also happens to Convincing interventions if they fail to replicate.
