Initially, a comparability study populations for inclusion will be made on all the variables collected at that time: socio-demographic and clinical (using Mantel-Haenszel test, the Chi-2 or accurate Fisher for qualitative variables, and Student's t test or ANOVA for quantitative variables) to reveal potential confounding factors to consider when analyzing the criteria of judgment. Comparisons between the study populations will also be conducted on all the criteria of secondary judgments. Adjustments will be made on the variables identified as confounding factors by conducting multivariate analysis (analysis of variance, multivariate logistic regression).
