There was no significant difference in the proportion of subjects carrying the CYP2C8*2 allele among subjects with recurrent infection within the 42-day follow-up in the AS–AQ arms (38.3 %; 95 % CI 30.1–47.2) compared to those with ACPR (31.1 %; 95 % CI 24.7–38.1); P = 0.19 (Table 2). The gene discussed is CYP2C8; the disease is infection.
