At T1, cachexia was strongly associated with elevated GDF15 (OR 4.29; 95% CI 1.04-29.74; <i>p</i> = 0.044) and IL-15 (OR 43.83; 95% CI 2.39->999; <i>p</i> = 0.007), whereas IL-4 had a protective association (OR 0.09; 95% CI 0.00-0.66; <i>p</i> = 0.013). The gene discussed is IL15; the disease is Cachexia.
