Survival Analysis of Cancer Events by Increased Serum Transferrin Saturation (>45%) and Levels of Iron Intake

Models	Hazard Ratio	95% CI
Model 1 (unadjusted)
Normal TS, low iron intake	1.00	1.00–1.00
Normal TS, high iron intake	0.75	0.55–1.01
Increased TS, low iron intake	1.02	0.69–1.49
Increased TS, high iron intake	1.74	0.78–3.85
Model 2 (adjusted)*
Normal TS, low iron intake	1.00	1.00–1.00
Normal TS, high iron intake	0.90	0.66–1.23
Increased TS, low iron intake	1.02	0.69–1.49
Increased TS, high iron intake	2.24	1.02–4.89

CI = confidence interval; TS = transferrin saturation.

* Adjusted for age, sex, race, smoking status, body mass index, and Charlson Comorbidity Index.
