Knee flexion active range of motion (AROM) reference curves, applied to: a the development set (from which the curves were derived), and b the test set (a temporally distinct sample of patients). The worst fitting model (GA) and best fitting model (BCCG) according to Schwarz Bayesian Criterion are displayed (a). The BCCG model is applied to the test set (b), and the percent of observations captured below each of the specified centiles is provided. The p-value, according to general z-test, describes the probability of the observed percentage, given the expected percentage. The average bias describes the mean difference between observed values and values predicted from the GAMLSS model
