Figure 3. Event Study Estimates of the Effect of Mandates for Annual Screening on Past Year Mammogram.

Figure 3

BRFSS 1987–2000, Adult Women 40–64

Figure 3 shows an event study for past year mammography. Time 0 is the time when each state implemented the first and only annual mandate for women of the relevant ages. The coefficients are those on dummies for each quarter before and after the law change in each state while also controlling for state and 5-year age groups, with the standard errors clustered at the state level, and using BRFSS weights. States are included only if they had only 1 law change and were in the BRFSS data for the whole 1987–2000 sample period.
