 Some specific results from the BMJ article include: "The efficacy of oral oseltamivir against symptomatic laboratory confirmed influenza was 61 % (risk ratio 0.39, 95 % confidence interval 0.18 to 0.85) at 75 mg daily ... The remaining evidence suggests oseltamivir did not reduce influenza related lower respiratory tract complications (risk ratio 0.55, 95 % confidence interval 0.22 to 1.35)". Notice especially the wide range for this second result.
