The statistical analysis revealed that age (OR 1.130; 95%CI 1.050–1.218; p = 0.001), NIHSS score on admission (OR 1.627; 95%CI1.329–1.992; p < 0.001), LDL-C (OR 3.196; 95%CI 1.516–6.742; p = 0.002) and NLRP3 inflammasome (OR 1.028; 95%CI 1.006–1.051; p = 0.012) were independent prognostic factors for poor outcomes in patients with cerebral infarction (Table 7). The gene discussed is NLRP3; the disease is cerebral infarction.
