Time (days) from symptom onset to all diary cards symptoms becoming mild or absent. Pairwise comparisons between patients with no treatment vs patients treated with oseltamivir (within 48 hours of symptom onset) or treated patient with a resistant virus. The study populations for this comparison are the same as those for the time to RNA not being detected, above. The smaller numbers are due to some patients not supplying a diary card or having no symptoms greater than mild at baseline. *There are only 47 resistant patients, 2 fewer than in the previous comparison (Fig 3) because one had only mild symptoms at baseline and one did not return a diary card. ^$Confidence limits could not be calculated for the untreated group due to the number of patients who were censored close to the final visit
