We did not find any association between the degree of brain injury as measured by the Glasgow coma score and CSF cytokine levels, however, IL-10 and IL-6 were inversely associated with tremors (Spearman rho -0.472, P< 0.03 and Spearman rho -0.45, P< 0.04 respectively). The gene discussed is IL10; the disease is Tremor.
