Statistical analysis
REGRESSION

Statistical analyses were performed using SPSS Statistics Version 28 (SPSS Inc., Chicago, Illinois, USA). Descriptive data were expressed as numbers with percentages and exact 95 %CI, with median and interquartile rage (IQR) for data with a skewed distribution, and mean (SD) for data with a symmetric distribution. Binomial univariate logistic regression was used to calculate differences between successful and unsuccessful treatment per variable.
