Variables associated with decannulation failure – results of multivariable binary logistic regression analysis (derivation set). Forest plot of variables independently associated with decannulation failure. One hundred and sixty-seven out of 426 patients (39.2%) in the derivation set failed decannulation. Multivariable regression models included candidate predictors with p values less than 0.2 in the univariable analysis.
