USINCHILD as predictor of resolution of fever*

Predictor variables	Haz. ratio	Standard error	95% conf. interval	p value
US Grade ∆¥ ≥ 1	2.3760	0.98	(1.0565–5.3436)	0.036
Age	1.0066	0.0425	(0.9266–1.0935)	0.876

*Defervescence time, expressed in hours, was chosen as expression of resolution of clinical signs

^¥US Grade ∆: difference between USINCHILD score after 48hours and at admission. Cox regression analysys of defervescence time.
