Clinical outcome: Binarised into excellent/good and fair/poor groups based on Cooney's score and calculated using ROC curves.
Clinical outcome: Binarised into excellent/good and fair/poor groups based on Cooney's score, and the ROC curve is used to calculate the age cut-off value.
Radiological results: ROC curves are used to calculate age cut-off values for the presence or absence of lunate fusion in simple X-rays.
Radiological results: Calculate the age cut-off value using the ROC curve for the presence of lunate fusion in simple X-rays.
