In the Research Letter titled “Trends in Pricing and Out-of-Pocket Spending on Entecavir Among Commercially Insured Patients, 2014-2018”,1 published January 21, 2022, an older version of the Figure was inadvertently published. The Figure included data points for out-of-pocket spending that incorrectly included a denominator of patients taking both brand name and generic entecavir, rather than generic only. This article has been corrected.1
