Study limitations
Summary

The publication reports a stepped-wedge protocol, not final efficacy or safety results. There is no placebo intervention. Participants and investigators know when treatment starts, although the photographic adjudication committee is blinded. No formal sample-size calculation was performed. The analysis plan models repeated severity measurements, but does not impute missing observations. Local application of a 1 mg/mL oral solution to lingual lesions is not equivalent to cutaneous QTORIN rapamycin 3.9% gel.
