Similarly, TSLP blood expression also exhibited significant differences when comparing the control group with patients (p < 0.001) and with all patient subgroups (CRSwNP without asthma: p < 0.001, N-ERD: p = 0.001, and asthmatics with CRSwNP: p = 0.041) (Table 2; Figure 1). Here, TSLP is linked to asthma.
