Error in Data Presentation in Text

JAMA Neurol. 2018;75(10):1287. doi:10.1001/jamaneurol.2018.2697

In the Research Letter titled “Timolol Eyedrops in the Treatment of Acute Migraine Attacks: A Randomized Crossover Study,” published online May 14, 2018, and in the August 2018 print issue of JAMA Neurology,1 there was an error in the presentation of data in the Results section. The fourth sentence should read, “The average percentage of headaches with a severity of none or mild at 2 hours was 57% with placebo compared with 78% with timolol.” This article was corrected online. This article was also corrected in July 2018 for errors in the Table and Results section.2
