The PAF was previously calculated for each included pathology, using the relative risks (RR) that were extracted from four different studies
aProportions are taken from the AIOM report, 2014
bRR is derived by calculating the mean value of the female and male RRs retrieved from previously published studies; GBD Global Burden of Disease, 2015; D DYNAMO-HIA, 2010; G Guh et al. 2009
