*The factor ‘specific chronic disease’ reflects the participants with single-morbidity, entered as a categorical variable with 15 categories (each category reflecting a specific chronic disease with no intrinsic order). Model A: explores the impact of the main effect of ‘specific chronic disease’ on fatigue severity. Model B: investigates the main effects of ‘specific chronic disease’ and the predisposing and associated factors (predictors) on fatigue severity. Model C: studies the impact of the main effects plus the interaction effect between ‘specific chronic disease’ and the predisposing and associated factors on fatigue severity.
