The sample size for the descriptive statistics and univariable regression models is n=2,970 counties (number of counties with acute HCV data) except for drug overdose deaths (n=2,704).
The final multivariable model includes drug overdose deaths per 100,000 population, therefore the sample size is n=2,704.
