Follow\u2010up ended at treatment switch\/discontinuation, NCO, end of enrollment, or September 30, 2022. NCOs addressed confounding for healthy users (wellness visit, herpes zoster vaccine, colon cancer screening, pelvic screening), functional status (accidents), and channeling. The 1\u2010year relative risk (RR) for each NCO was estimated for all treatment comparisons using an inverse probability of treatment and censoring weighted estimator.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In PsO, potential healthy user bias was detected in apremilast vs. IL\u201017i initiators, with a higher likelihood of herpes zoster vaccine and colon cancer screening (RR [95% CI]: 2.01 [1.41, 2.88] and 1.42 [1.13, 1.77], respectively). Wellness visits and pelvic exams were less likely among apremilast vs. topical initiators (0.84 [0.72, 0.98] and 0.83 [0.70, 0.98], respectively). The wellness visit RR was attenuated in individuals with \u2265\u20091 pre\u2010index topical prescription (0.90 [0.78, 1.04]).
