Summary

The retrieved publication is a protocol rather than a results report. It describes a matched-area, vehicle-controlled comparison during the first 12 weeks, followed by treatment of the whole malformation. The within-person design depends on the comparability of lesion areas and avoidance of treatment contamination between areas. The authors note that systemic absorption could reduce differences between treated and control areas. This 0.1% cream protocol does not establish the efficacy or safety of QTORIN rapamycin 3.9% gel.
