Fig. 4From: Association between dietary magnesium intake and gallstones: the mediating role of atherogenic index of plasmaMediated analysis model path diagram. Notes: Dietary magnesium intake was defined as the independent variable; gallstones as the dependent variable; and AIP as the mediating variable. Path a represents the regression coefficient of the association between dietary magnesium intake and AIP. Path b represents the regression coefficient of the association between AIP and gallstones. Path c represents the simple total effect of dietary magnesium intake on gallstones. Path c' represents the direct effect of dietary magnesium intake on gallstones when controlling for AIPBack to article page
