Anaemia patients had lower hepcidin concentration (x ̄=99.34 ng/mL) than non-anaemia patients (x ̄=331.43 ng/mL, p = 0.000694), with simultaneously higher IL-6 levels (x ̄=53.72 pg/mL) than non-anaemia patients (x ̄=24.64 pg/mL, p = 0.030727). The gene discussed is IL6; the disease is anemia (phenotype).
