“…( 66,67,71,72,77–86,90,91,93–95 ) Others used features extracted from images or collected from non‐imaging data. ( 68–70,73–77,87–89,92,96,97 ) Studies reported average best AUC of 0.92 (range 0.63 to 1.00) and average best accuracy of 89.8% (range 78.4% to 99.1%]. Surprising findings were that hospital‐related variables, such as the scanner device model, were better predictors of fractures than patients' characteristics or their images (AUC = 0.89 [95% confidence interval (CI) 0.87–0.91] versus 0.79 [95% CI 0.75–0.82] and 0.78 [95% CI 0.74–0.81], respectively), ( 77 ) which the authors acknowledged as a potential bias induced by the triage process.…”

“…( 82 ) Several studies did not report the confidence intervals or standard errors for the performance metrics that they reported. ( 66,68,69,72–74,79,81,83,84,86,88,89,92 ) Four studies obtained both high overall quality scores and near perfect AUCs (AUC ≥ 0.99). ( 78,79,91,94 ) Possible reasons for these unusual performances are the use of images' regions of interest ( 79,91 ) or the presence of potential data set bias, ( 78 ) which can significantly simplify the task.…”
