Error in Introduction

In the Original Investigation titled “Association Between Adolescent Preventive Care and the Role of the Affordable Care Act,”¹ published online November 6, 2017, there was an error in the Introduction section. The US Preventive Services Task Force recommendation for chlamydia should have been listed as grade B instead of grade A. The third sentence of the Introduction’s second paragraph should have read as follows: “Chlamydia screening, a US Preventive Services Task Force grade B recommendation, also remains low (47%-55% in 2014) among sexually active females ages 16 to 24 years.” This article was corrected online.
