"Looking at the Heart Protection Study (HPS) done in the UK, we used a technique for analysing survival time called RMST (restricted mean survival time). I won’t go into the details. The HPS study lasted for five years, and we calculated that the average increase in survival time was 15.6 days. This was at the end of five years of treatment (with a confidence interval of 5 days either side). For 4S, the figure was 17 days."
"Framing this slightly differently, what this meant was that taking a statin for one year, in the highest risk group possible, would increase your life expectancy by around three days."
"However, more recently the BMJ did decided to publish another paper entitled: ‘The effect of statins on average survival in randomised trials, an analysis of end point postponement.’
Results: 6 studies for primary prevention and 5 for secondary prevention with a follow-up between 2.0 and 6.1 years were identified. Death was postponed between −5 and 19 days in primary prevention trials and between −10 and 27 days in secondary prevention trials. The median postponement of death for primary and secondary prevention trials were 3.2 and 4.1 days, respectively."
