REGRESSION, MALNUTRITION
Nonnormally distributed data were expressed by the median (with the corresponding range) and normally distributed data by the mean (± standard deviation, SD).For univariable analysis, Mann–Whitey U test was applied to compare whether two independent groups are different. For comparisons within cross tabulations of two categorical variables with only two levels each, Fisher’s exact test was used. To examine relationships between variables that are either nominally or ordinally scaled with more than two expressions, chi-square test was applied.To model the association between malnutrition and its potentially influencing variables, four different logistic regression analyses were applied:For the first logistic regression model, all DVH parameters showing a Our fourth logistic regression model (dosimetric clinical model) consisted of the resulting parameter still showing To define cut-off values, the Youden index was derived from receiver operating characteristics (ROC).For multivariable logistic regression analysis and ROC with Youden index calculation, MedCalc (version 19.6, MedCalc Software Ltd, Ostend, Belgium) was used. All other calculations were performed with SPSS (version 28.0, IBM Corp., Armonk, NY, USA).All
