↵* Hospitalization rates presented are the numbers per 1000 infants who were hospitalized at least once during the first year (365 d) of life. Multiple admissions for different causes were treated as separate events, but multiple admissions for the same cause as 1 event. Unadjusted risk differences and risk ratios are shown.
