Can HLA-DRB4 Help to Identify Asthmatic Patients at Risk of Churg-Strauss Syndrome?

Table 2

Main HLA DRB1 findings in 159 asthmatics patients and 1808 blood donors. Values are the number of positive/2 × number of subjects (allelic frequency %) with the exception of the last two values (gene frequency for patients and controls).
