BCL2L12 and chronic rhinosinusitis with nasal polyps: To further explore the clinical factors associated with disease recurrence, we included the index of variance from Table 2 and Bcl2L12 mRNA levels in a binary regression model, as shown in Table 3, which showed that peripheral blood and tissue eosinophil counts, as well as tissue Bcl2L12mRNA levels were risk factors for CRSwNP recurrence.
