From: Ae index is an independent predictor of kidney stone recurrence in overweight and obese patients
A The relationship between Ae index and kidney stone recurrence was detected by smoothed curve fitting, and a non-linear relationship was found between them with an inflection point. The area between two blue lines is 95% CI. Each point of the red line represents an Ae index. B We plotted the ROC curves of Apo B, eGFR, and Ae index, respectively, and found the prediction accuracy of the Ae index was higher than that of Apo B and eGFR alone
