1: Creation of standard videos
A team of four reviewers1 went through the recorded videos and selected the standard videos for each score (0–3) of the four components of the BAT score. These videos were used as the ‘reference’
Step 2: Analysis of videos
Three independent outcome assessors2, masked to the group allocation then analyzed all the recorded videos by referring to the ‘reference’ videos. They submitted their scores to the principal investigator (A.T.)
Step 3: Assigning the final scores
The principal investigator assigned the final scores based on the concordance between the three outcome assessors – if the scores given by all three were the same, that score was recorded as the final score. However, if it was different, the three assessors reviewed the videos together to reach a consensus score. This score was then recorded as the final score
