 A Kaplan-Meier survival curves for mortality stratified by the presence and absence of CKD. B Kaplan-Meier survival curves for mortality stratified by the presence or absence of CKD and different levels of frailty in DM older adults. C Kaplan-Meier survival curves for mortality stratified by the presence or absence of CKD with a short or long TUG test in DM older adults. D Kaplan-Meier survival curves for mortality stratified by the presence or absence of CKD with fair or poor HGS in DM older adults. DM diabetes mellitus, CKD chronic kidney disease, RFI Rockwood frailty index, TUG timed up and go test, HGS handgrip strength. Poor HGS in women < 10.57 kg and men < 20.4 kg; Fair HGS in women ≥ 10.57 kg and men ≥ 20.4 kg. *P < 0.05, **P < 0.01
