LB and UB of 95% uncertainty interval (calculated as the 2.5 and 97.5 percentiles). Numbers (n, LB and UB) were rounded to the nearest full digit.
*Risk classification for relapse treatment is independent of the original risk classification for the first full course of treatment. There is a second risk assessment for children who relapse.
