Perirenal fat area is a preoperative predictor of hypertension resolution after laparoscopic sleeve gastrectomy: Generalized additive models

Table 3 The predictive value of perirenal fat area is superior to that of perirenal fat thickness

Fold	GAM (PrFA)	GAM (PrFT)
1	0.835 (0.669-1.000)	0.918 (0.817-1.000)
2	0.694 (0.443-0.945)	0.646 (0.371-0.922)
3	0.979 (0.932-1.000)	0.896 (0.771-1.000)
4	0.806 (0.547-1.000)	0.736 (0.554-0.918)
5	0.918 (0.792-1.000)	0.850 (0.704-0.997)
Mean	0.846 (0.676-0.989)	0.809 (0.643-0.967)

Fivefold cross-validation was used to evaluate the prediction accuracy of different generalized additive models including perirenal fat area or perirenal fat thickness respectively. GAM: Generalized additive model; PrFA: Perirenal fat area; PrFT: Perirenal fat thickness.
