Association between each symptom and assigned level of pain on multivariate analysis

Symptom	β*	se(β)†	p-value	pseudo-R2‡
Ear tugging	0.948	0.111	<0.001	0.115
Fussiness	0.879	0.113	<0.001	0.098
Sleeping difficulty	0.767	0.115	<0.001	0.075
Fever	0.749	0.115	<0.001	0.072
Eating less	0.674	0.116	<0.001	0.058
Playing less	0.642	0.117	<0.001	0.053

^*β = Slope oF the regression line, symptoms with higher β coefficients have a larger impact on pain levels

^†se(β) = standard error of the β coefficients

^‡Pseudo-R² assesses the proportion of variation in outcome “explained” by the model.
