In multivariable logistic regression analysis, factors significantly associated with severe anaemia were female sex (Adjusted Odds Ratio (AOR: 14.3, 95% CI: 2.14–126.6), albumin (AOR: 0.93 95% CI: 0.88–0.98) and creatinine levels (AOR: 1.01 95% CI: 1.00-1.03). The gene discussed is ALB; the disease is anemia (phenotype).
