Values for the control group (persons not selected in the lottery) are weighted means, and values for the lottery-winner group are regression-adjusted weighted means. P values are for two-tailed t-tests of the equality of the two means.
Lottery winners were adults who were randomly selected in the lottery to be able to apply for Medicaid coverage.
The data on age are for the age of the respondent at the time of the in-person interview. The study sample was restricted to persons who were between 19 and 64 years of age during the study period.
Race and ethnic group were self-reported. The categories of non-Hispanic race (white, black, and other) were not mutually exclusive; respondents could report as many races or ethnic groups as they wished.
