Table 2.

Area under curve (AUC) plotted by ROC for different ferritin value cut-offs for Group 2 and 3 (CKD cases)

Test	Ferritin_100	Ferritin _70	Ferritin_50	Ferritin_30
sTfR/log_f	0.918	0.961	0.974	0.960
sTfR	0.733	0.777	0.798	0.778
TIBC	0.574	0.552	0.544	0.548
per_SAT	0.391	0.399	0.410	0.429

sTfR/log_f: Ration of sTfR to log ferritin, sTfR: Serum transferrin levels, TIBC: Total iron-binding capacity, and per_SAT: Percentage saturation
