Fig 1.
Schematic representation of the two- part modelling process.
Fig1. shows the link between the SSB tax, changes in SSB consumption and BMI to the disease parameters and the life table. BMI is body mass index, x is age, i is incidence, p is prevalence, m is mortality rate, w is disability-adjustment, q is 1-year probability of dying, l is number of survivors, L is life years, and Lw is disability-adjusted life years. ‘-‘denotes a parameter without intervention and ‘+’ denotes a parameter with intervention.

Estimated change in energy intake and body weight after 20% tax.
Fig 2.
Change in the number of incident and prevalent T2DM cases over 20 years for males and females.
Cumulative reduction in in prevalence is plotted on the left vertical axis and annual reduction in incidence on the right vertical axis. T2DM is type 2 diabetes mellitus.
