a –Table shows coefficient estimate on age 19-25 quarterly admission/visit rates interacted with indicator for interim expansion period (2^nd and 3^rd quarters 2010) and post period (4^th quarter 2010-2011) in regression models of admission/visit rates controlling for age, quarter, and (where appropriate) sex. 95% confidence intervals are based on robust Huber-White standard errors, and p-values are based on two-tailed t-statistics.
