KCNMB1 Glu65Lys: Effect on BP and GFR in a primary care (Kaiser) population. GFR was estimated with the MDRD algorithm and mean ±1 SEM is shown. Numbers in parentheses (n) indicate the n for that observation. a Effects presented overall. The gene effect on GFR was determined by one-way ANOVA. b Role of BP status (higher vs. lower) and antihypertensive drug treatment. GFR was presented in 3 subgroups, high BP with/without antihypertensive medicines and low BP group. c Role of gene and sex. Effects were determined by two-way ANOVA.
