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

Figure 3 Perirenal fat area and perirenal fat thickness were correlated with the curve of postoperative hypertension resolution rates. Preoperative blood pressure and other factors were used as covariates, with perirenal fat area or perirenal fat thickness as independent variables and resolution rate as the outcome variable to construct a generalized additive model. The solid line represents the fitted values, and the shaded area indicates the 95% confidence interval. A: Using perirenal fat area as the independent variable; B: Using perirenal fat thickness as the independent variable. PrFA: Perirenal fat area; PrFT: Perirenal fat thickness.
