Labeling Errors in Flow Diagram

In the Original Investigation titled “Inhaled Corticosteroids Alone and in Combination With Long-Acting β₂ Receptor Agonists to Treat Reduced Lung Function in Preterm-Born Children: A Randomized Clinical Trial,” published online December 13, 2021, and in the February 2022 issue, there were labeling errors in the flow diagram. In the rightmost rectangle below the “53 Randomized” oval, the label reading “14 ICS with LABA” should have been “14 Placebo.” In the leftmost rectangle, the label reading “20 ICS with LABA” should have read “20 ICS.” This article was corrected online.
