Adjusted mean physiological measures among children before and after acute parent smoking intervention^a

Physiological measure	N	Intervention group (N = 20)			Control group (N = 21)			p value (difference)
		Time 1	Time 2	Difference	Time 1	Time 2	Difference
Heart rate	36	65.4	70.7	4.2	70.7	72.7	2.6	0.62
SBP	40	100.0	100.3	0.08	101.0	101.3	0.41	0.91
DBP	40	66.7	67.7	0.08	70.9	72.4	2.27	0.37
Exhaled carbon monoxide	37	3.9	3.7	−0.12	3.0	3.1	0.16	0.77

Note. SBP = systolic blood pressure; DBP = diastolic blood pressure.

^aAdjusted for child age, gender, and body mass index percentile. The difference scores are also adjusted for Time 1 values. The p value compares the adjusted mean differences between the Intervention and Control groups.
