a significant trendp < 0.0001
Irrespective of the equation applied for the derivation of eGFR and subsesquently the CKD grade, all HRs were significant, lower than unity for CKD grade 1 and greater than unity for CKD grade ≥3 with a significant trend p value from stage 1 to ≥3 ( p < 0.0001) and without any racial difference (0.11≤ p ≤ 0.98).
