The highest correlation on each parameter is bolded
Predictions from each model were binarized and the bone parameters were compared to the micro-computed tomography (µCT) ground truth. The values indicate Pearson correlations and the respective 95% confidence intervals
BV/TV = bone volume fraction, Tb.Th = trabecular thickness, Tb.Sp = trabecular separation, Tb.N = trabecular number
