Reporting of Noninferiority and Equivalence Randomized Trials: An Extension of the CONSORT Statement—Correction

JAMA. 2006;296(15):1842. doi:10.1001/jama.296.15.1842

Incorrect Formula: In the Special Communication entitled “Reporting of Noninferiority and Equivalence Randomized Trials: An Extension of the CONSORT Statement” published in the March 8, 2006, issue of JAMA (2006;295:1152-1160), a formula for a 2-sided confidence interval (CI) used to assess noninferiority of a new treatment compared with a standard one with regard to an outcome was incorrect. On page 1158 in the subsection titled “Elaboration” that reads “the upper bound of the 2-sided (1−α/2)  × 100% CI for the treatment effect has to be below the margin Δ to declare that noninferiority has been shown . . . ” should read “the upper bound of the 2-sided (1 −2α) × 100% CI for the treatment effect has to be below the margin Δ to declare that noninferiority has been shown . . . ”
