Nevertheless, periostin levels were significantly different (P = 0.001) according to endotypes, with mean values of 45.7 (27.9) ng/mL in allergic asthma, 64.7 (24.9) ng/mL in AERD, 59.0 (27.6) ng/mL in late-onset eosinophilic asthma, and 28.3 (13.3) ng/mL in non-eosinophilic asthma (see Figure 1B, Table 2). The gene discussed is POSTN; the disease is allergic asthma.
