A Lineage frequencies over time. Each line represents the estimated frequency of a particular pango lineage through time. In multinational logistic regression, each curve represents the change in the proportion of a given lineage over time. The shaded part represents the 95% confidence intervals of estimated. Only the estimated frequencies of variant were the top five are shown. The deadline of forecast model is July 14, 2023. B Lineage growth advantage. the estimated growth advantage for given pango lineages relative to lineage XBB.1.5. Vertical bars show the 95% HPD
