The figure in Table 2 shows the accompanying IRR and ORs on a logarithmic scale. Likewise, Table 3 shows the results for NIDD and their controls. The prevalence of travel-related diarrhea was 44% among IDD and 41% among controls. The incidence rate of travel-related diarrhea was 0.99 per person-month versus 0.74; the IRR showed no significant difference. The median number of days

with diarrhea was Luminespib 1.54 per month among IDD, comparable to controls. Diarrhea outcome measures before travel showed no significant differences between IDD and controls (p > 0.05) (data not shown). Diarrhea incidence rate and median number of symptomatic days were higher during travel than before travel, for both IDD and their controls (p < 0.05) (data not shown). The IDD and controls did not significantly differ in travel-related incidence rates and median number of symptomatic days for vomiting, fever, cough, rhinitis, and signs of skin infection. They also did not differ pre-travel, except that the median number of days with cough

Ferrostatin-1 mw was lower among IDD (p < 0.05) (data not shown). Travel-related and pre-travel outcome measures did not differ significantly, except that cough among IDD increased after departure in incidence rate and median number of symptomatic days (p < 0.05), although confidence intervals approximated 1 (data not shown). The prevalence of travel-related diarrhea was 39% among NIDD and 43% among controls. The incidence rate was 0.75 per person-month versus 0.70; the IRR showed no significant difference. The median number of days with diarrhea was 1.57 per month among NIDD, comparable to controls. Pre-travel diarrhea incidence rate and median number of symptomatic days were higher for NIDD than controls (p < 0.05) (data not shown). Diarrhea incidence rate and median number of symptomatic days were higher during travel than before travel for both NIDD and controls (p < 0.05) 4��8C (data not shown). Travel-related incidence rates and median number of symptomatic days for vomiting, fever,

cough, and rhinitis were comparable between both groups. The travel-related incidence rate and median number of days for signs of skin infection were higher among NIDD than among controls. However, these measures also differed before travel (data not shown) and showed no significant increase after departure (data not shown). Before travel, incidence rate and median number of symptomatic days for vomiting were higher for NIDD than controls (p < 0.05) (data not shown). Travel-related and pre-travel outcome measures did not differ significantly, except that rhinitis and vomiting among controls increased after departure in both incidence rate and median number of symptomatic days (p < 0.05) (data not shown). Only 6 out of 31 IDD with diarrhea (19%) and 5 out of 32 NIDD (16%) used the stand-by antibiotics.
