Poisson Regression Model for Count of TIs (> 72 h) in intervention vs. comparison groups for full intervention, pre-delivery, post-delivery periods

		Intention to treat (n = 131)						Per protocol (n = 53)
Time Period	Outcome	# TIs (I, C)^b	IRR	SE	*Z/chi-sq test*	p	95% CI	# TIs (I, C)^b	IRR	SE	*Z/chi-sq test*	p	95% CI
