Categorization of total daily physical activity and fragmentation index stratified at the median

	Cancer history		No cancer
	n	Mean (SD)	n	Mean (SD)	Threshold
Total daily physical activity (LTAC)	119	10.1 (0.6)	540	10.3 (0.6)	10.285
Low physical activity	77	9.7 (0.4)	253	9.8 (0.4)
High physical activity	42	10.7 (0.3)	287	10.7 (0.3)
Total fragmentation index score	119	0.29 (0.08)	540	0.27 (0.07)	0.264
Low fragmentation	41	0.21 (0.03)	289	0.22 (0.03)
High fragmentation	78	0.33 (0.06)	251	0.32 (0.05)

Note: LTAC = log-transformed total activity counts; representing transformed total activity volume; threshold column indicates the median used to categorize the total sample into low and high groups
