Errors in Figure 2 and Figure 3

In the Original Investigation titled "Effect of Nitrous Oxide as a Treatment for Subjective, Idiopathic, Nonpulsatile Bothersome Tinnitus: A Randomized Clinical Trial," published online August 2, 2018, there was an error the x-axis label and caption of Figure 2 and the key in Figure 3. In the x-axis, the labels read "Nitrous Oxide First" and "Placebo First." They should have been "Nitrous Oxide" and "Placebo." The caption included expansions of GBS and PI, which should not have been included. In Figure 3, the key indicates 'Nitrous oxide first" and "Placebo first." The key should have been "Nitrous oxide" and "Placebo." This article was corrected online.
