  1. Dependent variable for the logit model is a dichotomous indicator of whether a person has had health care during a particular year or not. Dependent variable for the OLS model is the number of health care use. t-score in parentheses ( ) and indicates significance level as follows: ***p ≤ 0.01, **0.01 < p ≤ 0.05, *0.05 < p ≤ 0.10. Confidence intervals are presented in brackets [ ].
