  1. This table summarises how patients transition between BTS/SIGN steps from one time interval (T-1) to the next time interval (T). For example, 9.0% of paediatric patients in step 5 in the previous time interval (T-1) had moved to step 4 by time interval T. Similarly, 5.4% of adult patients in step 3 in the previous time interval (T-1) had moved to step 1 by time interval T
  2. Bold formatting indicates the most common transition in each step
