C3a levels differed significantly across the groups (p = 0.0186), with higher values in the group with cachexia and inflammation (median 102.4 ng/mL, IQR 89.4–158.0) in comparison to the group with cachexia without inflammation (median 81.4 ng/mL, IQR 47.9–124.0) and the group without cachexia (median 61.6 ng/mL, IQR 46.8–86.8). The gene discussed is C3; the disease is Cachexia.
