Fig. 3From: Higher estimated net endogenous acid production with lower intake of fruits and vegetables based on a dietary survey is associated with the progression of chronic kidney diseaseSix-year trends in mean urine pH by NEAP levels. Solid squares and open triangles represent mean values, and vertical lines represent standard deviations. Because the interaction between time and NEAP was not significant, we estimated the overall difference in mean urine pH between the two NEAP groups, which was estimated to be 0.228 (95% confidence interval, 0.044 to 0.412, p = 0.016).
