Table 2.
IQR, P values, and AUCa for usage variables.
| Variables | No support (n=30), median (IQR) | Support (n=31), median (IQR) | Mann-Whitney-Wilcoxon test, P value | Effect size AUC (rating) |
| Timeb in app (minutes) | 102 (67-267) | 122 (57-231) | .72 | 0.53 (null) |
| Timeb in exposure (minutes) | 41 (3-113) | 27 (6-106) | .91 | 0.49 (null) |
| Number of points | 155 (50-410) | 185 (60-510) | .52 | 0.55 (null) |
aAUC: area under the receiver operating characteristic curve.
bAll time variables were measured in seconds but are presented here in minutes for ease of interpretation.
