The H-L test indicates the calibration of the logistic regression model (whether the expected and observed probabilities of anal fissure are similar). This would be when p > 0.05. On the other hand, the AUC is used to measure the discriminatory power of the model (range: 0.5–1). Values around 0.7 are considered to be satisfactory. If we obtain a good calibration and discrimination, the results would correctly explain the association between anal fissure and personal traits. AUC, area under the ROC curve; CI, confidence interval; H-L, Hosmer-Lemeshow test; OR, odds ratio.
