IL17A and asthma: In addition, to assess correlation in normal population, this parameter was calculated for patients and results showed that unlike absence of correlation in patients with mild asthma (r=0.451; p-value=0.106) (Figure 2B), there was a significant correlation (r=0.790; p-value=0.001) between IL-10 and IL-17A transcription level in severe asthma (Figure 2C).
