Fig. 2From: Association between lower serum bicarbonate and renal hyperfiltration in the general population with preserved renal function: a cross-sectional studyAssociation between the percentile rank of serum bicarbonate level and the odds of renal hyperfiltration after adjustment for possible confounding variables (see Methods for details). A multivariate logistic regression model was used to compute point-wise estimates and confidence intervals of odds ratio curves. The solid line represents the adjusted odds ratio and the shaded area the 95 % confidence intervalBack to article page
