Statistical tests results to evaluate the difference between Kaplan–Meier survival functions for the first indication of cryptosporidiosis (oocysts shedding and/or clinical signs) in neonatal calves either treated with halofuginone lactate or untreated and kept in either individual or in group pens.

Outcome	Population of calves	Variable	Log-rank	Peto–Peto–Prentice
Onset of oocysts excretion detected by PCRa	Individual pen	Halofuginone vs placebo	<0.001	0.001
	Group pen	Halofuginone vs placebo	0.008	0.014
	Halofuginone	Individual pen vs group pen	0.007	0.020
	Placebo	Individual pen vs group pen	0.40	0.35
Onset of diarrhoea	Individual pen	Halofuginone vs placebo	0.005	0.024
	Group pen	Halofuginone vs placebo	0.07	0.12
	Halofuginone	Individual pen vs group pen	0.20	0.29
	Placebo	Individual pen vs group pen	0.05	0.26
