Estimates of transmission parameters for each HCV subtype.

1The phylodynamic transmission parameter PTP = N/(NeT) has been estimated as the coefficient of the linear regression of N versus NeT without constant term. For the confidence intervals the autocorrelation structure of each variable has been taken into account according to the Newey-West correction.
2Generation time estimated as Var(Z)/PTP (maximum estimate assuming that the minimum proportion of transmitters equals the proportion of IDUs in each subtype).
3Proportion of transmitters, practically equal to the proportion of IDUs within each subtype.
4Upper 1% of the distribution of secondary infections including transmitters and non-transmitters.
