In the Original Investigation titled “Identification and Validation of Plasma Metabolomic Signatures in Precancerous Gastric Lesions That Progress to Cancer,”[1] published June 22, 2021, there were errors in a column of 95% CI values in Table 1. The odds ratios were correct, but each 95% CI given in the OR (95% CI) column under the IM/LGIN vs SG/CAG heading within the Validation set section was incorrect. This article has been corrected.[1]
