Several factors in logistic regression, such as obesity (OR 7.200, p=0.003), segmented neutrophils (OR 1.145, p=0.015), GMCSF (OR 2.220, p=0.015), IL-15 (OR 1.332, p=0.031), IL-2 (OR 3.089, p=0.025), and zonulin levels (OR 2.573, p=0.003), presented significant OR values greater than 1 in the crude analysis, which indicate an association with higher odds of mortality. The gene discussed is CSF2; the disease is obesity due to melanocortin 4 receptor deficiency.
