<p>Meteorological conditions and air pollution concentrations in 1998</p

Excess risk (ER) % in the never/seldom exercise group, and difference in excess risk (ΔER)% of mortality associated with each 10% increase in influenza intensity for low/moderate and frequent exercise relative to the never/seldom exercise.

<p>ER% were assessed by Poisson regression, and ΔER% were assessed by multinomial logistic regression, negative values indicate odds reduction vs never/seldom exercise (P-values: ^*<0.05 ^**<0.01 ^***<0.001 ^****<0.0001); ‘Never/Seldom’ means adults who never exercised or exercised less than once per month, ‘Low/Moderate’ means adults who exercised at least once per month to three times per week, and ‘Frequent’ means adults who exercised four times or more per week</p
