Retraction: Evaluation of respiratory muscle training interventions on pulmonary function in critical care: a systematic review and meta-analysis

After publication, post-publication review revealed that the article [1] contained a substantial number of irrelevant citations and, in some cases, lacked appropriate citations (e.g., [9], [10],[11], [12], [13], [21]). These irrelevant citations compromise the validity of the background and discussion sections and undermine the overall trustworthiness of the published work. Accordingly, the editors have decided to retract the article. The authors have been notified of this retraction and have agreed to it. They apologize for the oversight, which arose from insufficient verification of the relevance of references during the literature selection and manuscript preparation process.
