When videolaryngoscopy documentation is based on laryngeal view alone, it does not reliably reflect the performance of tracheal intubation. We evaluated this relationship and the reproducibility of a structured classification framework for videolaryngoscopic tracheal intubation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a prospective multicentre observational study across 44 hospitals. Videolaryngoscopic tracheal intubations were assessed independently by an airway operator and an observer using a three\u2010domain classification: blade geometry; glottic view using the percentage of glottic opening (POGO) score; and tracheal tube delivery. Inter\u2010rater reliability was assessed. The relationship between glottic view and tracheal tube delivery was analysed across predefined POGO categories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 5302 tracheal intubations with paired assessments were analysed.
