From: Epidemic history of hepatitis C virus genotypes and subtypes in Portugal
Exponential mean growth rates for the most prevalent HCV subtypes (1a, 1b, 3a, 4a and 4d*) found in the current study. Linear regression equations were derived from the mean growth rates within the exponential phase of the Bayesian skyline plots (BSP) of each subtype as shown in Fig. 2. *Contains additional GT4d sequences (n = 14) from a previous study in Portugal.
