17 Aug 2004 Learn how to use a known relative risk reduction to es- timate the risk concepts and presented tabular tools and equations to help clinicians 

Where zeros cause problems with computation of the relative risk or its standard error, 0.5 is added to all cells (a, b, c, d) (Pagano & Gauvreau, 2000; Deeks & Higgins, 2010). In epidemiology, the relative risk reduction (RRR) or efficacy is the relative decrease in the risk of an adverse event in the exposed group compared to an unexposed group. It is computed as. ( I u − I e ) / I u {\displaystyle (I_ {u}-I_ {e})/I_ {u}} , where. Relative risk is based on the probabilities of risk for two different groups as follows.Relative risk = group-1-probability / group-2-probability Example #1 People who smoke have a 10% lifetime chance of developing a particular type of cancer. Relative to Workplace and Process Safety, risk and the risk equation can be represented as: A combination of the consequences (I.e., outcome) of an event (including changes in circumstances) and the associated chance of something happening (I.e., likelihood or probability).
