TFRC and coinfection: Table 4 shows the hematological and inflammation data for school-aged children, stratified by 1-year age increments. Children aged 8 years with P. falciparum-hookworm coinfection had significantly higher Hb concentration and lower median values of sTfR, sTfR/log ferritin ratio, and AGP than those infected with P. falciparum alone.
