Notes:
^a Wang et al. calculated the disability weight of hypertension in China based on a large-scale data from many sources
^b In 2004, WHO measured the disability weight of diabetes as 0.015 with 95%CI of 0.012 to 0.018
^c Hepatic diseases usually include viral hepatitis, chronic hepatic diseases and hepatic cancer. In this study, we used the mean value of decompensated liver cirrhosis (the lower limit value) and viral hepatitis to measure the disability weight
