- aOdds ratio between coated ETT and standard ETT (ratio of the odds of being in the lower categories). The model controls for baseline for the parameters Cough and Painful throat but due to non-convergence, baseline was not included in the Dry mouth and Hoarseness models. The Proportional Odds Model was only applied to the symptoms/problems when not all patients within a treatment group were in the same category
