Receipt of infant HIV DNA PCR test results is associated with a reduction in retention of HIV-exposed infants in integrated HIV care and healthcare services: a quantitative sub-study nested within a cluster randomised trial in rural Malawi

Table 3 Cox regression model assessing the effect of intervention and outcome of infant HIV PCR results on the hazard of non-retention in the subgroup of mothers who received their infant’s HIV test results. Note: the mothers of 10 infants received a HIV-positive test result

Parameter	Test	Infant (n = 507)		Mother (n = 507)
Parameter	Test	Hazard ratio (95%CI)^a	P-value	Hazard ratio (95%CI)^*	P-value
PCR results	Positive	3.12 (1.57,6.2)	< 0.001	1.66 (0.56,4.91)	0.361
Treatment arm	MIP^b vs SOC^c	0.88 (0.42,1.85)	0.739	1.15 (0.65,2.04)	0.625
