GSTM1 and Iron deficiency anemia: Similarly, compared to Control-Beans, there were no significant Fe-Bean effects on dichotomous outcomes, including anemia (<12 years: Hb <11.5 g/dL; ≥12 years: Hb <12.0 g/dL)), iron deficiency (SF <15.0 μg/L; TBI <0.0 mg/kg; sTfR >8.3 mg/L), or inflammation (CRP >5.0 mg/L; AGP >1.0 g/L).
