Boxplots represent the mean (dots), median (black line), quarter and third quartile (upper and lower edges of the box), maximum (upper edge) and minimum (lower edge) of hospitalized cases for each scenario. In figure a–c the simulated curves in the above scenarios basically overlapBack to article page
