Case-mix and MICS-adjusted HRs (95% CIs) of all-cause mortality across 18 different combinations based on change in serum ferritin and baseline serum ferritin (a ) in the no IV iron use group (n = 3,354) and (b ) in the IV iron use group (n = 90,290). Reference group was stable serum ferritin (−100 to <100 ng/mL/quarter) and baseline serum ferritin 200 to <500 ng/mL.
