Survival analyses and their applications in orthopaedics

James A Pruneski et al. Knee Surg Sports Traumatol Arthrosc. 2023 Jun.

Abstract

Survival analyses are a powerful statistical tool used to analyse data when the outcome of interest involves the time until an event. There is an array of models fit for this goal; however, there are subtle differences in assumptions, as well as a number of pitfalls, that can lead to biased results if researchers are unaware of the subtleties. As larger amounts of data become available, and more survival analyses are published every year, it is important that healthcare professionals understand how to evaluate these models and apply them into their practice. Therefore, the purpose of this study was to present an overview of survival analyses, including required assumptions and important pitfalls, as well as examples of their use within orthopaedic surgery.

Keywords: Outcomes; Risk; Statistics; Survival analysis; Time-to-event.
