  • aPR = adjusted prevalence ratio; NHIS = National Health Interview Survey; PSA = prostate-specific antigen; SDM = shared decision making.

  • Note: Each model is adjusted for: age, survey year, race/ethnicity, educational attainment, insurance type, immigration status, and geographic region.

  • ↵a Model includes 2,592 men; 487 men excluded from each model based on missing educational attainment and immigration data.

  • ↵b Statistically significant at P <.05.

  • ↵c Model includes 1,752 men; 352 men excluded from each model based on missing educational attainment and immigration data.

  • ↵d Model includes 4,246; 169 men excluded from each model based on missing educational attainment and immigration data.
