Age group (years)	Year	Incidence			Prevalence			Deaths			DALYs			YLLs			YLDs
		Number of cases	Rate (1/100,000)		Number of cases	Rate (1/100,000)		Number of cases	Rate (1/100,000)		Number of person-years	Rate (1/100,000)		Number of person-years	Rate (1/100,000)		Number of person-years	Rate (1/100,000)
Abbreviations: DALYs=disability-adjusted life years; YLLs=years of life lost; YLDs=years lived with disability. * Percent change (%) was calculated as difference value between 2019 and 2000 divided by quantity in 2000.
