a
Based on Russian national statistics (Khokhryakov et al. 1996)
b
Based on fitting the HRR model (Equation 1 used) to the data in column 4.
c
Expected (predicted) average RR based on the HRR model when the baseline B = 0.00095; results are averaged over each dose range indicated and have not previously been reported.
