Fig. 8: Tornado charts showing the sensitivity of the variables on the different metrics.
From: The estimated annual financial impact of gene therapy in the United States
a Tornado chart of the impact of the variables on the peak value. b Tornado chart of the impact of the variables on the cumulative spending (both nominal and discounted). c Tornado chart of the impact of the variables on the date of peak value. Since we compute by calendar month, a small machine precision error may change the results by 1 month. The black bars represent the effect of increasing the variable by 20% and the red bars represent the effect of decreasing the variable by 20%.
