Table 4.

Comparison of sources of support (all participants combined), human-centered trial.

	Support friends/family	Support dog	Support research
Mean answer	4.4 (1.55)	4.8 (1.57)	5.5 (1.46)

The mean and standard deviation (SD) answers to the three sources of support: “dog,” “friends/family,” and “participating in research,” on a scale of 1 to 7, where 1 is “totally disagree,” 4 is “neutral,” and 7 is “totally agree.” All answers were included regardless of group allocation, as there was no significant difference between groups in any measured parameter.
