Thinking about risk, what do we mean by absolute risk and relative risk Sounds a bit like the level of risk can be presented in a way that gives a particular impression of a greater or a lessor risk or benefit? Are there occasions when a vested interest might want to give an impression of an increased benefit, or reduced risk from an intervention? How could choosing RRR versus ARR influence the impression given for adverse reactions is medical journals? Conversely Are there occasions when a vested interest might want to give an impression of a decreased risk from an intervention? So will RRR always be higher than ARR? Why can the RRR vary between populations and vary over time? So using one of the two measures to estimate the risk/benefit ratio would lead to different conclusions? How could risk / benefit reporting be optimised in the medical literature? Do you think the editors of prestigious international journals are aware of the differences between RRR and ARR?
