Odds ratios (OR) on the association between influenza A infection and influenza-like illness score and pulmonary embolism with corresponding 95% confidence intervals (95% CI). Crude OR are adjusted for age, COPD (= chronic obstructive pulmonary disease) and asthma. We did not calculate the odds ratio for influenza B, because there were only few infected patients (0 in the case group, 3 in the control group). | ||
