2.7.1. Description of the Population
Patients were described according to their clinical and epidemiological characteristics. We collected socio-demographic and clinical characteristics of the study patients at inclusion. Verification of the initial comparability of the groups resulting from randomization was also performed. Quantitative characteristics were summarized as mean and standard deviation or median and interquartile range, depending on the skewness of the distribution. Qualitative variables were described using the number of patients in each modality and their percentages.
