This project involved a systematic literature review of published trials of treatments for moderate-to-severe plaque psoriasis. Data was extracted from the publications on various psoriasis endpoints including the Physician Global Assessment (PGA), Dermatology Life Quality Index (DLQI), and Short-Form 36 (SF-36). A traditional meta-analysis and a mixed treatment comparison was conducted on the extracted data.
