<p>Assessment of POCD required completion of seven cognitive assessments which were not all completed for all individuals at all timepoints. Presence/absence of POCD was therefore determined as follows throughout the trial. Week 1: Intervention group – 19, Control group – 28; Week 12: Intervention group – 24; Control group – 33; Week 52: Intervention group 27; Control group – 32.</p
