Incorrect Equivalent Dose and P Values in Figure 3

In the Original Investigation titled “Effect of 12 mg vs 6 mg of Dexamethasone on the Number of Days Alive Without Life Support in Adults With COVID-19 and Severe Hypoxemia: The COVID STEROID 2 Randomized Trial,”¹ published in the November 9, 2021, issue of JAMA, there was an incorrect equivalent dose listed and incorrect P values in Figure 3. In the second paragraph of the article, the last sentence should have been “Pharmacodynamic studies suggest dose-dependent activation of the corticosteroid receptor with increasing doses up to 60 mg of prednisone (equivalent to 9 mg of dexamethasone).¹⁰” In Figure 3, a coding error was recently detected revealing that the majority of P values were incorrect. In the last column of Figure 3, the P values should have been .32 instead of .57; .76 instead of .83; .31 instead of .53; .36 instead of .44; .13 instead of .59; and .25 instead of .64.
