^aMortality rate calculated as the number of subjects who died at each group, divided by the person-years (PY) of follow up. Rates were calculated per 1000 PY.

^bPopulation Mortality Rates, adopted from 2004 national life table for Iran, reported by Khosravi et al.¹⁴.

^cIt was calculated by this formula: $\mathrm{Ln}\left(\widehat{\mathit{RR}}\right)\pm \mathit{z}\sqrt{\frac{({\mathit{n}}_1-{\mathit{x}}_1)/{\mathit{x}}_1}{{\mathit{n}}_1}+\frac{({\mathit{n}}_2-{\mathit{x}}_2)/{\mathit{x}}_2}{{\mathit{n}}_2}}$. Then we took the antilog (exp) of the lower and upper limits.
