However, an overview of current applications and critical appraisal to peer-reviewed guidelines is lacking. The objectives of this study are to 1) provide an overview of current ML prediction models in orthopaedic trauma; 2) evaluate the completeness of reporting following the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) statement; and 3) assess the risk of bias following the Prediction model Risk Of Bias Assessment Tool (PROBAST) tool.\u003Cbr>Methods\u003Cbr>A systematic search screening 3,252 studies identified45 ML-based prediction models in orthopaedic trauma up to January 2023. The TRIPOD statement assessed transparent reporting and the PROBAST tool the risk of bias.\u003Cbr>Results\u003Cbr>A total of 40 studies reported on training and internal validation; four studies performed both development and external validation, and one study performed only external validation. The most commonly reported outcomes were mortality (33%, 15/45) and length of hospital stay (9%, 4/45), and the majority of prediction models were developed in the hip fracture population (60%, 27/45) . The overall median completeness for the TRIPOD statement was 62%(interquartile range 30 to 81%). The overall risk of bias in the PROBAST tool was low in 24%(11/45), high in 69%(31/45), and unclear in 7%(3/45) of the studies. High risk of bias was mainly due to analysis domain concerns including small datasets with low number of outcomes, complete-case analysis in case of missing data, and no reporting of performance measures.\u003Cbr>Conclusion\u003Cbr>The results of this study showed that despite a myriad of potential clinically useful applications, a substantial part of ML studies in orthopaedic trauma lack transparent reporting, and areat high risk |\n\nSystematic review of machine-learning models in orthopaedic trauma 9  \nH.

Otherwise, there will remain a sizeable gap between the development of ML prediction models and their clinical application in our day-to-day orthopaedic trauma practice.  \nTake home message  \n• Useful applications of machine-learning prediction models in orthopaedic trauma exist, but a substantial proportion lack external validation and transparent reporting, and are at high risk of bias.  \nIntroduction  \nMachine learning (ML) has shown great potential in aiding clinicians with different tasks in orthopaedic trauma. 1,2 Specific ap","cbCaibVRKWr0oxYR","https://ap.wps.com/l/cbCaibVRKWr0oxYR","pdf",1305324,1,11,"English","en",105,"# Aims\n# Methods\n# Results\n# Conclusion\n# Take home message\n# Introduction","[{\"question\":\"What is the main aim of this systematic review?\",\"answer\":\"The review provides an overview of machine-learning prediction models in orthopaedic trauma and evaluates both reporting completeness using TRIPOD and risk of bias using PROBAST.\"},{\"question\":\"How many studies were included and how were they identified?\",\"answer\":\"A systematic search screened 3,252 studies, ultimately including 45 ML-based prediction model studies up to January 2023.\"},{\"question\":\"What did the review find about reporting completeness and risk of bias?\",\"answer\":\"Overall median TRIPOD completeness was 62%, while PROBAST showed low risk of bias in 24% of studies, high risk in 69%, and unclear risk in 7%.
