Memory tested by the 15-WVLT. Tertiles of the 15-WVLT: best tertile mean 42.6 (SD 6.3) n = 51; middle tertile mean 29.7 (SD 2.8) n = 54; worst tertile mean 21 (SD 3.9) n = 50 Δ EGFR available for n = 41, n = 48, n = 39. Ankle-Brachial index available for n = 35, n = 37, n = 39. Walking speed available for n = 46, n = 50, n = 47. Model I: linear regression including correction for age, gender and educational level. *In model I age is only adjusted for gender and educational level; gender is only adjusted for age and educational level; educational level is only adjusted for age and gender
