Numbers of Patients Transposed in Text

In the Original Investigation entitled “Effect of Pressure Support vs T-Piece Ventilation Strategies During Spontaneous Breathing Trials on Successful Extubation Among Patients Receiving Mechanical Ventilation: A Randomized Clinical Trial,”¹ published in the June 11, 2019, issue of JAMA, patient numbers were transposed in a sentence in the Results section of the text. The first sentence in the Secondary Outcomes subsection on page 2178 should have read “After the first SBT, 532 patients (92.5%) undergoing the 30-minute PSV SBT and 486 patients (84.1%) undergoing the 2-hour T-piece SBT were extubated (difference, 8.4%; 95% CI, 4.7%-12.1%; P < .001).” This article was corrected online.
