  • All models are adjusted for individual age, gender, baseline number of physician visits and number of admissions to hospitals, EA-level mean household income, CT-level percentages of each of black residents, recent immigrants (within the last 5 years) and residents living in the same house over the previous 5 years and forward sortation area. SEs are adjusted for within-EA clustering. 95% confidence intervals are shown in parentheses.

  • *Statistically significant at 0.05 level.

  • †Statistically significant at 0.10 level.

  • EA, enumeration area; MI, myocardial infarction; SEP, socioeconomic position.
