Association between the severity score and the change in weight and WHZ

	1-Month change in weight (g)	1-Month change in WHZ (z-score)
Low severity	Reference	Reference
Medium severity	−25.4 (−63.0, 12.2)	−0.008 (−0.052, 0.036)
	(p=0.186)	(p=0.720)
High severity	−132.2 (−213.6, −50.7)	−0.171 (−0.266, −0.077)
	(p=0.001)	(p<0.001)

The association between incident episodes of diarrhoeal classified as low (score 0), medium severity (score 1–6) and high severity (score ≥7) and the change in weight and WHZ over 1-month intervals is shown below. Age (same fractional polynomials as in symptom-specific models) and season (sine and cosine terms) were also adjusted for (β coefficients not shown).
