aO = treatmet trial 150 mg oseltamivir daily during 5 days in adults, elderly; dosage adjusted to weight in children; prophylaxis trial = treatment dosage/2.bZ = treatmet trial 2×10 mg inhaled zanamivir daily during 5 days in adults, elderly; dosage adjusted to weight in children; prophylaxis trial = treatment dosage/2.codds ratio and risk difference (Wang).dno pooling of results.eGRADE quality of evidence: high; moderate; low.ITT = intention-to-treat; NI = neuraminidase inhibitor; CI = confidence interval.
