CD40LG and infection: The following optimal and reliable multicharacter model was developed, with all statistical coefficients being significant (p = 0.007 for intercept, p < 0.001 for predictors, adjusted R2 = 0.9339 for this model, F statistic = 66.03, and p = 6.06 × 10−11 for the general significance level of the model):(1)X=−1.671+0.624A+0.350B+ 0.007C−0.007D + 1.146Ewhere X is the IgM level, A is the Intebio® intake factor, B is the SE infection factor, C is the AST level, D is the ALP level, and E is the CHOL content.
