  1. Values are presented as median (IQR). Absolute change (no brackets) and relative (percentage) change (in brackets) are based on the difference between post-neoadjuvant CRT (week 0) and pre-neoadjuvant CRT (baseline) within each group. All data is averaged over the 72-h period of PA monitoring. Note: due to an upgrade in software during data collection, sleep efficiency is reported in 7/23 (exercise) and 7/10 (usual care control)
