ANGPT2 and chronic kidney disease: There was no difference in the Ang-2/Ang-1 ratios (Figure 1C) between control and pre-dialysis CKD individuals but it was significantly higher in dialysis patients compared with the other groups (means±SD in controls 0.8±0.7, pre-dialysis CKD patients 1.2±0.7 and dialysis patients 2.5±1.4 ng/ml, p<0.0005 in comparisons between dialysis and both the other groups)
