Gallbladder and biliary tract cancer burden trends in Brazil, Russian Federation, India, China, and South Africa in 1990-2021

Figure 6 Observed and predicted trends of the age-standardized incidence rate of gallbladder and biliary tract cancer globally and in Brazil, Russian Federation, India, China and South Africa nations from 2022 to 2040 using the Bayesian age-period-cohort model. A: Male; B: Female. The shadow in the figure represents uncertainty intervals, suggesting that mortality could fluctuate dramatically as the corresponding rates rise or fall by 1% per year, with each shade corresponding to a change of 1%. ASIR: Age-standardized incidence rate.
