(Level A rating requires at least two consistent Class I studies.)* Moderate (B) Probably effective, ineffective, or harmful (or probably useful/predictive or not useful/predictive) for the given condition in the specified population. (Level B rating requires at least one Class I study or two consistent Class II studies.) Weak (C) Possibly effective, ineffective, or harmful (or possibly useful/predictive or not useful/predictive) for the given condition in the specified population. (Level C rating requires at least one Class II study or two consistent Class III studies.) Insufficient (U) Data inadequate or conflicting ; given current knowledge, treatment (test, predictor) is unproven. * In exceptional cases, one convincing Class I study may suffice for an "A" recommendation if 1) all criteria are met, 2) the magnitude of effect is large (relative rate improved outcome is greater than 5 and the lower limit of the confidence interval is greater than 2).
