Data Errors in Table 3

JAMA. 2018;320(21):2272-2273. doi:10.1001/jama.2018.17900

In the Original Investigation titled “Effect of Early Surgery vs Physical Therapy on Knee Function Among Patients With Nonobstructive Meniscal Tears: The ESCAPE Randomized Clinical Trial,”1 published in the October 2, 2018, issue, the upper limits of 95% CIs were incorrectly reported as positive rather than negative numbers in Table 3. The between-group differences for the arthroscopic partial meniscectomy vs physical therapy groups overall, at 6 months, and at 24 months should have been reported as −5.9 (95% CI, −10.3 to −1.4), −8.2 (95% CI, −14.1 to −2.3), and −7.7 (95% CI, −14.0 to −1.3) points, respectively. Also, the P value for the between-group difference for the delayed arthroscopic partial meniscectomy vs physical therapy group at 6 months should have been .009. This article was corrected online.
