Note: CI = confidence interval, EAC = excess attributable cases, PAR = population attributable risk.
*Numbers rounded to nearest case.
†Values for Total (men and women combined) were estimated based on excess attributable cases estimated for men and women separately and not directly from population attributable risk models. For this reason, no confidence intervals are available, and totals may not match individual totals for men and women.
