Time (days) from symptom onset to first laboratory record with influenza A RNA not detected. Pairwise comparisons between patients with no treatment vs patients treated with oseltamivir (within 48 hours of symptom onset) and vs treated patient with a resistant virus. Both treated and untreated populations included patients infected by influenza A viruses, with no detection of resistant viruses. *The 49 resistant patients comprise 40 patients infected with H3N2 or H1N1pdm09 who developed resistance during the study plus 9 patients infected with seasonal H1N1. All 49 patients were in the treated group. Three patients (2 with H1N1pdm09 and one with H3N2) developed oseltamivir resistance during the study but were not treated until Day 3. These patients are not included in this comparison as they do not meet the definition
