Table 2.

Cumulative survival probabilities, Hazard Ratios and median time to dental practice attendance for families assessed by health visitors

	Cumulative survival probabilities	Hazard ratios [95% CI]		Median time to participation [95% CI]
Group 1 HV: YES; DHSW: YES N = 5087	0.88	1.87	[1.8 to 1.9]	8.8	[8.5 to 9.1]
Group 2 HV: YES; DHSW: NO N = 6408	0.82	1 (ref)		17.8	[17.1 to 18.6]
Group 3 HV: NO; DHSW: NO N = 23,741	0.81	0.98	[0.9 to 1.0]	18.4	[18.1 to 18.7]

GROUP 1 are those whom the health visitor referred for DHSW intervention and received the intervention. GROUP 2 are those whom the health visitor referred for DHSW intervention but did not receive the intervention. GROUP 3 are those whom the health visitor perceived to not need a DHSW intervention and so they were neither referred nor received the intervention
