HRs (95% CIs) of all-cause mortality across the 18 different combinations based on change in serum ferritin and baseline serum ferritin with (a ) drop in IV iron use group (n = 50,808) and (b) rise in IV iron use group (n = 36,533) in case-mix and MICS adjusted models. Reference group was stable change in serum ferritin (−100 to <100 ng/mL/quarter) and baseline serum ferritin 200 to <500 ng/mL.
