Notes The available study report is a 29‐page document in Japanese. The design and methods are similar to those of WV 15670 and 15671 (the "pivotal" treatment trials in adults) and the trial was intended as a "bridge" with the Western trial programme. The report does not contain any supporting data (i.e. statistical analysis plan, protocol, amendments, certificates of analysis and audit, randomisation lists, lists of investigators, IRB clearance and individual listings)

Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) High risk Not specified as protocol and methods section were not available
Allocation concealment (selection bias) High risk Not specified as protocol and methods section were not available
Incomplete outcome data (attrition bias) 
 Symptoms High risk 92 participants excluded in efficacy analysis because infection with influenza virus could not be verified in the efficacy analysis
Incomplete outcome data (attrition bias) 
 Complications of influenza High risk 92 participants excluded in efficacy analysis because infection with influenza virus could not be verified in the efficacy analysis
Incomplete outcome data (attrition bias) 
 Safety data High risk No drop‐outs because of harms were reported but no breakdown by on‐ and off‐treatment status reported
Selective reporting (reporting bias) High risk Not specified as protocol and methods section were not available
Other bias High risk Not specified as protocol and methods section were not available
