Cycle data was collected on the dates specified in 'measurements'. Postoperative positive 4AT score percentage refers to the percentage of postoperatively assessed patients who had a 4AT score of 4 or greater, it does not include those patients not tested. As adhesive 4AT tools were introduced in cycle 2, data for them appears only from cycle 2 onwards.
