  1. eGFR: estimated glomerular filtration rate. eGFR is given as least-square mean ± S.E. adjusted for age, body mass index; eGFR is given as least-square mean ± S.E. adjusted for age, body mass index, habitual smoking, alcohol consumption, coffee consumption and antihypertensive medication use. Bonferroni correction for multiple comparisons was used.
