Data presented as means±SD (range). Regression coefficients β (with standard error) were derived from a multivariable linear regression model adjusted for the interaction between sex and residence (village). Statistical significance was set at P≤0.05 and is marked in bold.

Hb, hemoglobin; HCT, hematocrit; MCHC, mean corpuscular hemoglobin concentration; MCV, mean corpuscular volume; N, number of participants; RBC, red blood cell count; RDW, red cell distribution width.
