Table 2.

Linear regressions showing the association between (a) changes in heart rhythm parameters between baseline and following the intervention (M3) (used as dependent variable, separated model for each heart rate parameter) and (b) museum-based art activity (used as independent variable) in participants (n = 53).

Change in heart rhythm parameters between M0 and M3*	β	[95% CI]	p-value
Full day	−6.2	[−10.8; −1.6]	0.010
Active hours†	−2.4	[−7.6; 2.8]	0.358
Inactive hours‡	−4.1	[−10.2; 1.9]	0.173

β, coefficient of regression beta; CI, confident interval; all models adjusted on baseline characteristics of participants (please see Table 1).

^*Calculated from the formula [((M3 value – M0 value)/((M3 value + M0 value)/2)) × 100]; ^†Between 12 pm and 6 pm; ^‡Between 12 am and 6 am; p-value significance (i.e., <0.05) indicated in bold.
