Errors in Secondary Outcomes

In the Original Investigation titled “Effect of Moderate Hypothermia vs Normothermia on 30-Day Mortality in Patients With Cardiogenic Shock Receiving Venoarterial Extracorporeal Membrane Oxygenation: A Randomized Clinical Trial,”¹ published in the February 1, 2022, issue of JAMA, there were errors in the reported secondary outcomes. In the Results section of the abstract, the third sentence should be “For the composite outcome of death, heart transplant, escalation to left ventricular assist device implantation, or stroke at day 30, the adjusted odds ratio was 0.57 (95% CI, 0.36 to 0.90; P = .02) for the moderate hypothermia group compared with the normothermia group and the risk difference was −12.7% (95% CI, −23.2% to −3.2%).” In the Results section of the text, under the Secondary Outcomes heading, first paragraph, the second and third sentences should be “The composite outcome (death, heart transplant, escalation to LVAD implantation, or stroke) was significantly different between groups at day 30 (adjusted OR, 0.57 [95% CI, 0.36 to 0.90], P = .02; risk difference, −12.7% [95% CI, −22.3% to −3.2%]). The risk difference for the composite outcome at day 60 was −9.8% (95% CI, −20.9% to 1.3%) and at day 180 was −9.8% (95% CI, −21.9% to 2.3%) (Table 2).” In Table 2, under the Secondary Outcomes heading, composite outcome of death, heart transplant, escalation to LVAD implantation, or stroke, all 3 rows of data at 30, 60, and 180 days were revised as well as the data in footnotes e through g. This represented 4 additional composite end points in the hypothermia group and 7 events in the normothermia group. The list of nonauthor collaborators was also updated to correct incorrect tagging. This article was corrected online.
