¹Multivariable logistic regression of the model of the relationship between CHr and iron deficiency anaemia (CHr only).

²Multivariable logistic regression of model of the relationship between %HYPO and iron deficiency anaemia (%HYPO only).

The 2 models corrected for gender, age, stage of disease. OR: Adjusted odds ratio. Early stage: Stages 1–3; Late stage: Stages 4 and 5.ID: Iron deficiency NID: Non-iron deficiency.
