  1. Legend: NACA = National Advisory Committee for Aeronautics Score. Calculated with McNemar-Bowker test. Dark grey fields display worsened (higher) NACA scores, the diagonal numbers display no change, light grey display improved (lower) NACA scores within the same mission. Patients with missing NACA 2nd were excluded, hence the different number of included patients.
