Dermoscopic Response Predictors in Papulopustular Rosacea Treated with Topical Ivermectin and Metronidazole: A Prospective Observational Comparative Study.

Of the 9 metronidazole patients without baseline PFPs, 8 (89%) achieved at least a partial improvement (including all 4 optimal responders in this arm), whereas only 1 patient without PFPs showed no significant response, but this did not reach statistical significance ( p = 0.176), likely due to small sample size ( Figure 1 ).
