Test of Difference in Black and White LDCT Screening Proportions at a Community-Based Cancer Center

	Black	White	χ² (p-value)
*Comparison Group*
Number of cigarette smokers age 55 and older in the cancer center’s county	4204 (27%)	11362 (73%)
*Study Group*
Number of LDCT-screened individuals^*	19 (7.3%)	243 (92.7%)	51.41 (p<.0001)

During the study period, 265 patients were screened. Because only two Hispanic patients and one Native American patient were screened, we restricted our cohort to the remaining 262 Black and White patients. As a result, the comparison group was also restricted to Black + White individuals only to mirror LDCT screened patients.

Note: LDCT = low-dose computed tomography
