Table 2 Association between influenza and pulmonary embolism.

From: Influenza infection and risk of acute pulmonary embolism

 

Odds ratios (OR) and 95% confidence intervals (95% CI)

 

Crude OR (95% CI)

Adjusted OR (95% CI)

Influenza A

0.22 (0.03–1.67)

0.22 (0.03–1.72)

Influenza-like illness

1.28 (0.75–2.18)

1.16 (0.67–2.01)

  1. 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).
