Antiviral therapy is effective in fighting hepatitis C | Letters

The Cochrane review that you highlight analysed clinical trials, which are by nature short term, where the sole purpose was to evaluate the virological efficacy of new antiviral drugs.The trials were neither designed, nor powered, to assess mortality, so it is hardly surprising that the Cochrane review was unable to identify any impact on mortality.Regulatory authorities and clinicians all recognise that clearing hepatitis C virus reduces mortality.
