Fig. 6From: The clinical and virological features of the first imported case causing MERS-CoV outbreak in South Korea, 2015Root-to-tip genetic divergence plotted against the sampling date. The genetic distances from the root were calculated on the maximum likelihood phylogeny. Each y-axis value represents the genetic distance from the tip to the root, and the x-axis value represents the corresponding sampling date of the tip. The points and regression dotted line shown were obtained from the ML tree presented in Fig. 4. The R2 value is indicated above the regression line Back to article page
