The current approach to assessing the quality of evidenceobtained from clinical trials focuses on three dimensions: thequality of the design (with double-blinded randomised controlledtrials representing the highest level of such design); the statisticalpower (beta) and the level of significance (alpha). While theseaspects are important, we argue that other significant aspects oftrial quality impinge upon the truthfulness of the findings: biologicalplausibility, reproducibility and generalisability.
