title: Crowdsourcing for research data collection in rosacea.
abstract: Several medical crowdsourcing sites are available to patients online, but few studies in the literature have compared crowdsourced data to clinical trials. Herein, we compare data from rosacea patients from a major medical crowdsourcing site with those from randomized controlled trials.
