Table 2.

Crude and adjusted effects of personal CO exposure on BP. The associations are the estimated change in SBP or DBP (mmHg) associated with a 1 ppm increase in mean 72-hour-averaged personal CO exposure.

	Crude Association^a		Adjusted Association^a,^b
	Estimate (mmHg)	95% CI	Estimate (mmHg)	95% CI
SBP	0.31	[−0.28, 0.91]	0.39	[−0.12, 0.90]
DBP	0.59	[0.14, 1.03]	0.43	[0.01, 0.86]

Standard Errors are cluster-robust. In each model, results are reported after removal highly influential variables with Cook’s Distance > 0.04; maximum number removed observations = 2.

Adjusted for age, BMI, gestational age, occupation, secondhand smoke exposure, and day of week of BP measurement.
