Table 1.
Estimated chronic kidney disease (CKD) prevalence in Austria between 1989 and 2008 by sex; eGFR was calculated using the CKD-EPI 2009 [30] and revised 2021 [31] equation. Continuous variables are summarized by mean (SD) or median [IQR] and tested via student’s t or Mann-Whitney‑U tests, categorical variables are summarized by counts (%) and tested via χ2-test
| Men 42.4% (N = 16,891) | Women 57.6% (N = 22,909) Total N = 39,800 |
