AMSTAR-PF is the only quality appraisal tool specifically designed for systematic reviews of prognostic factor studies. Post-testing modifications to AMSTAR-PF were restricted to guidance notes and minor question wording, leaving the overall structure and 14 domains unchanged. AMSTAR-PF was adapted from AMSTAR 2 through a multistage development process involving experts in prognostic factor reviews, evidence synthesis, and quality appraisal tool development. Six of the 19 AMSTAR-PF questions additionally allow a Not Applicable response. AMSTAR-PF consists of 14 domains and 19 specific questions, each with four answer options: Yes, Probably Yes, Probably No, and No.
