Table 3 summarizes the results of logistic regression analysis (odds ratio and associated 95% confidence intervals) unadjusted and adjusted for sex, age, SaO2%, smoking, obesity, and preexisting conditions (model 1), and by these same previous covariates with the addition of D-dimer and CRP levels (model 2). This evidence concerns the gene CRP and obesity due to melanocortin 4 receptor deficiency.
