Additionally, the odds of anaemia were high in PSC of the age group 6–11 months (aOR = 4.40; 95% CI: 1.82–10.61); P = 0.0003, in PSC with a history of fever in the last two weeks (aOR = 1.58; 95% CI: 1.04–2.39); P = 0.0324, in children with high levels of AGP (aOR = 2.13; 95% CI: 1.36–3.34); P = 0.0010, those with iron deficiency (aOR = 2.37; 95% CI: 1.40–4.02); P = 0.0014, and those with alpha-thalassemia disease (aOR = 4.08; 95% CI: 1.74–9.59); P = 0.0004. The gene discussed is ATP5MK; the disease is anemia (phenotype).
