The main endpoint was death or tracheostomy. Univariate Cox regression analysis was conducted for all the NCS parameters. Subsequently, multivariate analysis was performed using Cox stepwise regression, incorporating factors identified in the univariate analysis and known prognostic factors. Kaplan\u2013Meier curves and log\u2010rank tests were used for survival analysis.
