Table 1 — Table 1.

Parameter estimates (Est.) with 95% confidence intervals (CI) for the changes (Δ) in Hb_mass, ferritin and transferrin saturation (TSAT) during prolonged moderate altitude exposure, when controlled for oral iron supplement dose.

Fig 1 — Fig 1.

Iron incorporation into the iron storage (SII) and red cell compartment (HII) for each category of iron supplement dose [0 mg (n = 15), 105 mg (n = 144), 210 mg (n = 19)].
Overall, total iron incorporation (TII) was higher in iron-supplemented athletes compared with non-iron supplemented athletes.
