Odds ratios for elevated levels of all coagulation factors with the P80 in the control population used as cut off levels (cutoff levels are mentioned in Table 1). Odds ratios are adjusted for age and sex.
Odds ratios for elevated levels of all coagulation factors using the P90 in the control population as cutoff levels (again, cutoff levels are mentioned in Table 1). Odds ratios are adjusted for age and sex.
Air indicates odds ratios for individuals who had traveled by air; and other indicates odds ratios for individuals who had traveled by bus, train, or car. Odds ratios are adjusted for age and sex.
