Data extraction was guided by the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews for Prediction Modelling Studies (CHARMS). The Prediction model Risk of Bias Assessment Tool (PROBAST) and the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD\u2010AI) were used to evaluate risk of bias and reporting, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifteen studies were included after full\u2010text screening, comprising of 490 models incorporating a variety of predictors. The most frequently used predictors were demographic variables (age, gender, BMI), genetic markers (HLA\u2010B27, HLA\u2010B08, HLA\u2010C*06), clinician and patient\u2010reported outcomes (PASI, DLQI), clinical features and lifestyle factors. Nine studies used machine learning methods, such as Bayesian probabilistic methods and random forest, whilst the remainder used traditional statistical approaches such as regression and risk scores. The C\u2010statistic ranged from 0.53 to 0.99. Calibration, where reported, was modest and sensitivity and specificity were reported in seven studies, often with inconsistent thresholds and reporting. Only three studies performed external validation, which reduced discriminative performance, raising concerns about generalizability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Future studies should incorporate a variety of predictors to develop comprehensive models that reflect the aetiology of Psoriatic arthritis whilst ensuring adequate reporting and validation in external cohorts to allow assessment of model performance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jdv.70561","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T13:24:31Z","timestamp":1781789071000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prognostic prediction models for psoriatic arthritis in psoriasis: A systematic review"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3369-3408","authenticated-orcid":false,"given":"Fatimah","family":"Khoda","sequence":"first","affiliation":[{"name":"The Dermatology Centre, Salford Royal Hospital, Northern Care Alliance NHS Foundation Trust Manchester Academic Health Science Centre  Salford UK"},{"name":"Division of Musculoskeletal and Dermatological Sciences, School of Biological Sciences, Faculty of Biology, Medicine and Health The University of Manchester  Manchester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasmin","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Dermatology St Mary's Community Health Campus  Portsmouth UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William W.
