  1. For the questions on time since last screening, the sample study participants are restricted to those whose HIE data as well self-report indicated receipt of screening. Results in columns 1 and 2 are listed as marginal totals and are statistically significant at 1% level of significance for Colonoscopy, Pap test and Mammogram. Gwet’s probabilistic benchmarking method according to the Landis and Koch scale of reliability is: -1.0–0.0 (Poor), 0.0–0.2 (Slight), 0.2–0.4 (Fair), 0.4–0.6 (Moderate), 0.6–0.8 (Substantial), 0.8–1.0 (Almost Perfect) [23]. The measures in all the columns are adjusted for sampling weights
