  1. Notes. PR = standardized prevalence ratio, CI = confidence interval. Confidence intervals were derived from the Mantel-Haenszel χ2 test. All adjustments were internal and direct, using this study’s population of colon cancer cases as the standard. A prevalence ratio of 1.00 was the between-place baseline. Middle and high poverty neighborhood payer prevalence estimates were compared to payer prevalence estimates in low poverty places.
  2. a Number of incident colon cancer cases.
  3. b Prevalence estimates were age-adjusted across these categories: 25–59, 60–69, 70–79 and 80 or older.
