IL6 and asthma: In addition, the TNF-α levels were higher in the asthma patients with nocturnal symptoms (3.39 ± 1.90 vs. 2.09 ± 1.80 pg/ml, p = 0.043), but the between-group differences in the inflammatory cytokines, except IL-6 (adjusted p = 0.022), were not statistically significant after correction using the Benjamini–Hochberg method (Table 2).
