  1. Note: Reference categories are female, non-Hispanic White, 0 chronic conditions, and year 2013. Coefficients are interpreted as percentage point changes with probability of outcome scaled from 0 to 100. For example, the coefficient of − 0.056 for PCP visits among urban dual eligibles means that each PCP visit is associated a lower risk of ACSC hospitalization by 0.056 percentage points
