Correlations of fractional iron absorption. Correlations between fractional iron absorption (FIA) and serum ferritin (SF) (A and B), transferrin saturation (TS) (C and D) and hepcidin (Hep) (E and F) of the participants separated.by the variants in the TMPRSS6 rs855791, CC (○, n=35) and TT (□, n=44). Each point represents one participant and their mean of FIA, SF, TS, and Hep measured on study day 1 (D1) and D3. Pearson’s correlation factors r for FIA to SF correlation are: -0.79 (P<0.001) and -0.45 (P=0.002); for FIA to TS correlation: -0.45 (P=0.006) and -0.14 (P=0.360); for FIA to Hep correlation: -0.81 (P<0.001) and - 0.45, (P=0.002), for the CC variants and TT variants respectively. **P<0.001, *P<0.05,
