Note that there were different response rates for different questions, resulting in different denominators. “Patients with symptoms” refers to the number of patients having the particular symptom compared with the total number of patients answering the question yes or no on the questionnaire. This column provides data on the overall frequency of symptoms. Isolates for further analysis were not available for all patients answering the comprehensive questionnaire. Data in the section “Association of C. jejuni strain characteristics with symptoms…” contains symptom information from patients from whom isolates were obtained and were typed. The frequencies with which each symptom was associated with the presence of absence of the CJIE1 prophage and also the presence within the CJIE prophage of ORF11 have been compared to determine whether either CJIE1 alone or CJIE1 with ORF11 have any significant effect on patient symptoms compared with absence of the prophage.
