Table 5. Numbers of participants in non-diabetes and diabetes groups based on their CKD stages.

CKD stage	Non-Diabetes N = 65	Diabetes N = 76
Stage1 (GFR ≥90 mL/min/1.73m2)	46	34
Stage2 (60≤GFR<90 mL/min/1.73m2)	18	21
Stage3 (30≤GFR<60 mL/min/1.73m2)	1	12
Stage4 (15≤GFR<30 mL/min/1.73m2)	0	6
Stage5 (GFR<15 mL/min/1.73m2)	0	3

GFR values for 19 patients were unavailable.

Fisher’s exact test was used to test for differences in CKD stages between diabetics and non-diabetics, p < 0.001.
