In contrast, within the All Low class, depression scores were positively correlated with soluble IL-10 (r = 0.53, p = 0.035, n = 17) and sleep disturbances scores negatively correlated with soluble IFN-γ (r = −0.33, p = 0.042, n = 40). The gene discussed is IFNG; the disease is depressive symptom measurement.
