Table 1.

Transitions from one interval (T-1) to the next (T) by treatment step

Paediatric patients To: (Time interval T)
Step 5 Step 4 Step 3 Step 2 Step 1
From: (time interval T-1) Step 5 59.1% 9.0% 4.9% 11.6% 15.5%
Step 4 0.3% 87.9% 1.2% 2.7% 8.0%

Adult patients To: (time interval T)
Step 5 Step 4 Step 3 Step 2 Step 1
From: (time interval T-1) Step 5 76.8% 12.0% 4.1% 2.0% 5.2%
Step 4 0.7% 91.4% 1.9% 0.8% 5.2%

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

Bold formatting indicates the most common transition in each step
