In the Original Investigation titled “Effect of Regional vs General Anesthesia on Incidence of Postoperative Delirium in Older Patients Undergoing Hip Fracture Surgery: The RAGA Randomized Trial,” published in the January 4, 2022, issue of JAMA, some numeric values were incorrect in Table 2 (the risk difference values originally reported as 0 should have included the 95% CI, 0 to 0; and for the blood transfusion row, the unadjusted risk difference should have been −0.2 [95% CI, −4.3 to 5.2], the adjusted risk difference for center should have been −0.1 [95% CI, −5.3 to 4.1], and the risk difference for age, preoperative delirium, preexisting dementia, and center should have been −0.1 [95% CI, −4.9 to 5.2]), Table 3 (the risk difference values originally reported as 0 should have included the 95% CI, 0 to 0), and in eTable 4 in online Supplement 3 (no unadjusted relative risk values should have been reported for the categories of DRS-r-98 severity score, worst pain score VAS within 7 days, or length of hospital stay). The article and supplement have been corrected online.
