From page 391...
... calculations require numerical inputs for the specific incidence of disease, the proportion of disease incidence leading to disability, the average age of disability onset, the duration of disability, and the distribution of disability across six levels of severity. Because such data are often unavailable, determinations of burden typically incorporate estimates for most of these values.
From page 392...
... The lack of data on psychiatric disorders in many countries has led to estimates based on methods that might not be transferable to assess the health status of the global poor. Further work is needed on standardizing assessment indicators to obtain a more realistic view of the burden of disease affecting developing countries.
