Fig. 4From: Development and validation of non-invasive prediction models for migraine in Chinese adultsCalibration curves of eight prediction models for migraine in the training set. The Hosmer–Lemeshow tests showed that models 1 to 7 had excellent calibration (P for H–L test > 0.05), but the calibration of model 8 was not very good (P for H–L test = 0.049 < 0.05).
