As in Table 3, four variables were considered independently associated with MoCA, while the others were excluded from the model (p > 0.1): in particular, the duration of infection was negatively associated with cognitive impairment (OR: 0.96, 95%CI: 0.93–0.99, p = 0.0099), while age (OR: 1.12, 95%CI: 1.07–1.17, p < 0.0001), ALT (OR: 1.02, 95%CI: 1.01–1.04, p = 0.0262), and PHQ-2 (OR: 1.33, 95%CI: 1.11–1.60, p < 0.0001) were positively associated with cognitive impairment (AUC: 0.725, standard error: 0.03, 95%CI: 0.66–0.78). The gene discussed is DOCK3; the disease is infection.
