This table summarizes the robustness check results using different samples and specifications as indicated at the very left. Each estimate in columns (1), (5), and (9) comes from a separate regression and shows the effect of peer behavior on individual screening participation. Columns (3), (7), and (9) show the mean of the dependent variable, and columns (4), (8), and (12) show the number of observations. All regressions control for past healthcare utilization (screening participation, outpatient expenditure, days in hospital), wage, age, place of residence, job type, business sector, firm location, firm size, and year of job move. Standard errors clustered at the firm level are shown in parentheses, *$p<0.05$, **$p<0.01$, and ***$p<0.001$
