Table 3.

Correlation (Spearman ρ) between number of support messages/support persons and app engagement (all groups combined).

Variable	Number of messages, ρ (95% CI)	P value	Number of people, ρ (95% CI)	P value
Time in app (seconds)a	0.17 (–0.05 to 0.37)	.13	0.31 (0.10 to 0.49)	.004
Time in exposure (seconds)	0.08 (–0.13 to 0.29)	.45	0.26 (0.05 to 0.44)	.02
Number of points	0.21 (–0.00 to 0.40)	.05	0.30 (0.09 to 0.48)	.005

^aAlthough time variables are presented elsewhere in the paper in terms of minutes for ease of interpretation, our analyses were conducted in terms of seconds, so that is how our data are presented in this table.
