[Correspondence] Oseltamivir for influenza

Joanna Dobson and colleagues1 present an individual patient meta-analysis assessing the efficacy of oseltamivir for the treatment of influenza infection. The authors report that the data for their analysis were acquired from Roche Pharmaceuticals via a secure web portal. Interestingly, the data presented differ substantially from the data reported by the Cochrane Collaboration in their review of clinical study reports.2 Five trials had populations common to both analyses for comparison, and differences in admittance to hospital reported are presented in the table.
