Healthcare use in participants with methamphetamine-associated PAH

Outcome	Incidence Rate Ratio (95% CI)	P Value
Unadjusted
Emergency department visit	2.30 (1.71–3.10)	<0.001
Hospitalization	1.39 (1.10–1.76)	0.005
Adjusted for age, sex, race/ethnicity, education, body mass index, and the time-dependent covariate of whether the participant was on PAH-specific therapy or not
Emergency department visit	2.30 (1.71–3.11)	<0.001
Hospitalization	1.42 (1.10–1.83)	0.007

Definition of abbreviations: CI = confidence interval; PAH = pulmonary arterial hypertension.

Data are presented as incidence rate ratio of emergency department visits/hospitalizations in the preceding 6 months with 95% CI between participants with methamphetamine-associated PAH as compared with participants with idiopathic PAH, as quantified by generalized estimating equations using a Poisson distribution. Models adjusted for age, sex, race/ethnicity, education, body mass index, and the time-dependent covariate of whether the participant was on PAH-specific therapy or not.
