Correct and incorrect reclassification from GFR categories based on eGFR_cr or eGFR_cys to categories based on eGFR_cr-cys in patients with eGFR_cys<eGFR_cr and eGFR_cys>eGFR_cr

Reclassification	Replacing GFR Categories Based on eGFRcr by eGFRcr-cys		Replacing GFR Categories Based on eGFRcys by eGFRcr-cys
	eGFRcys<eGFRcr eGFRcys >20% Lower Than eGFRcr	eGFRcys>eGFRcr eGFRcys >20% Higher Than eGFRcr	eGFRcys<eGFRcr eGFRcys >20% Lower Than eGFRcr	eGFRcys>eGFRcr eGFRcys >20% Higher Than eGFRcr
