Notes. 95% confidence intervals in parentheses.
The rows of the table include marginal effects from a multivariate panel data regression on the condition level indicating changes in health care utilization 1 and 2 years after REGARDS enrollment. The first rows indicate change in doctor visits for diagnosed conditions, and the latter rows indicate change in doctor visits for undiagnosed conditions. The columns indicate 6 regression specifications. All specifications include the control variables noted in the text. In columns 2, 3, 5, and 6, estimates are adjusted for hospitalizations. In columns 4 through 6, estimates are adjusted for time‐invariant individual characteristics using individual‐by‐condition fixed effects. In columns 3 and 6, background trends in doctor visits are allowed to vary with participants’ biomarkers measured at the time of REGARDS enrollment.
