Labeling Errors in Figure

In the Original Investigation titled “Assessment of Cumulative Incidence and Severity of Primary Open-Angle Glaucoma Among Participants in the Ocular Hypertension Treatment Study After 20 Years of Follow-up,” published in the May 2021 issue of JAMA Ophthalmology,¹ 4 rows in the table below the graph in Figure 2A were incorrectly labeled. The rows labeled “Observation” should have been labeled “Medication,” and the rows labeled “Medication” should have been labeled “Observation.” This article was corrected online.
