Notes. aUnadjusted adequate provider data definition means calculation of unadjusted vaccination rates were based on original 2011-2013 definition of adolescents having adequate provider data in the NIS-Teen for those years. Adjusted adequate provider data definition means calculation of unadjusted vaccination rates were based on adjusted definition of adolescents having adequate provider data in 2011-2013, as per new definition proposed in 2014 and after; therefore, only vaccination rates for 2011-2013 should differ between unadjusted and adjusted adequate provider definitions (grayed rows).
Abbreviation: CI, confidence interval.
