Renal Function and Death in Older Women: Which eGFR Formula Should We Use?

Table 1

Prevalence of eGFR category using 4 different estimating equations.

eGFR category, mL/min/1.73 m^2	GFR estimating equation, (%)
	BIS1	CKD-	BIS2	CKD-
≥75	159 (12.3)	622 (48.3)	182 (14.1)	432 (33.5)
60 to <75	495 (38.4)	358 (27.8)	498 (38.6)	430 (33.4)
