Age (years)	Odds ratio for influenza when cough is present (95 % CI)^a
60	1.3 (0.4, 4.6)
65	2.2 (0.9, 5.7)
70	3.8 (1.8, 8.2)

CI Confidence interval
^aOdds ratio was adjusted for all other predictors in the final model: hospital site, wheezing, feverishness, confusion, frailty, time to triage from symptom onset, exposure to person with influenza-like illness, influenza activity in the community, product term of confusion and frailty, and product term of cough and age. Cough was based on chart-review and self-report
