ORs present the binary association between the indicated variable and iron-deficiency diagnosis. Adjusted ORs present the multivariate association between serum iron result and diagnosis, with all covariates included in the model.
MCH, mean corpuscular haemoglobin; MCHC, mean corpuscular haemoglobin concentration; MCV, mean corpuscular volume; RDW, red cell distribution width; TSAT, transferrin saturation.
