Changes in Health Insurance Coverage and Lung Cancer Screening at Age 65: A RD Analysis

	Men			Women
	Age 63–64	RD at Age 65		Age 63–64	RD at Age 65
Outcome	Baseline	Unadjusted	Adjusted	Baseline	Unadjusted	Adjusted

P		0.02	0.003		0.03	0.05
People with lower risk (do not meet USPSTF criteria)	91.2	6.0 (2.6–9.3)	5.6 (2.3–8.8)	92.0	6.1 (3.3–8.8)	6.5 (3.9–9.2)
P		<0.001	<0.001		<0.001	<0.001
Lung cancer screening
People with high lung cancer risk (meet USPSTF criteria for screening)	11.1	14.8 (0.7–28.9)	16.2 (2.4–30.0)	18.2	2.7 (−20.0 to 25.4)	1.6 (−19.8 to 23.0)
P		0.04	0.02		0.82	0.88
People with lower risk (do not meet USPSTF criteria)	4.0	4.3 (−0.1 to 8.6)	3.7 (−0.5 to 8.0)	4.5	3.8 (0.1–7.5)	3.9 (0.3–7.6)
P		0.05	0.09		0.05	0.04

The columns include findings from stratified analyses, including only men or women as noted in the headlines. Models were centered at 65, so estimates apply to age 65. “Unadjusted” estimates control only for age. Models allowed age trend terms to vary above versus below the cutoff. Adjusted estimated regression discontinuities at age 65 adjusted for respondents’ age, race, employment status, income level, education level, veteran status, state of residence, state’s Medicaid expansion status, and year of the interview. 95% confidence intervals calculated using robust SEs are in parentheses.

RD indicates regression discontinuity; USPSTF, US Preventive Services Task Force.
