  1. PRAL, potential renal acid load; NEAP, net endogenous acid production; BMI, body mass index
  2. ** Unemployed participants were retired or jobless individuals
  3. Data are presented as mean ± SD or number (percent)
  4. P values are from one way analysis of variance (ANOVA) test for quantitative and Chi-square or Fischer exact tests for qualitative variables comparisons across tertiles of dietary acid load, respectively
