	Art therapy (n = 22)	Music reminiscence activities (n = 24)	Control (n = 22)
Number of participants assessed at 3 months	19	23	NA
Number of participants assessed at 9 months	18	22	18
Mean change at 3 months from baseline (SE)	197 (197)	−41 (186)	NA
Mean change at 9 months from baseline (SE)	552 (177)	292 (163)	573 (182)
Difference (intervention – control) (90% CI) [p]	− 22 (− 444, 400) [0.932]	− 281 (− 686, 124) [0.252]

Mean values were estimated using a linear mixed-effects model adjusted for baseline values and gender. See “Methods” section for outcome definitions

NA not applicable (telomere length was not collected in the control group at 3 months post baseline), SE standard error, CI confidence intervals
