Following publication of the article [1], it was noted that in Table 1 postoperative diaphragmatic parameters (including thickening fraction, diaphragm excursion (QB), diaphragm excursion (DB), diaphragm excursion fraction, and diaphragm excursion difference) in PORC (Post-operative residual curarization) group and non-PORC group have been swapped with each other by mistake. Table 1 in this correction article is the correct version. We apologize for any inconvenience caused by this error.

Clinical characteristics and baseline ultrasound indicators between patients with and without residual neuromuscular blockade.
