Abbreviations: BG, blood glucose; FSL-Pro, FreeStyle Libre Pro; HD, hemodialysis; ISFG, interstitial fluid glucose; MAD, mean absolute difference; MARD, mean absolute relative difference; NA, not applicable; SMBG, self-monitoring blood glucose.
Glycemia was classified based on the blood glucose values of self-monitoring blood glucose.
a
P < .0001 vs iPro2 for mean absolute difference.
b
P < .0001 vs iPro2 for mean absolute relative difference.
