ATP5MK and anemia (phenotype): All of the indicators except zinc were also affected by systemic inflammation; higher AGP was associated with a greater risk of low plasma retinol [1.58 (1.38, 1.83)], elevated TfR [1.18 (1.03, 1.33)], and anemia [1.29 (1.12, 1.49)], and with a lower risk of low ferritin [0.62 (0.54, 0.70)].
