Fig. 4: Feature associations with depression by behaviour type.
From: Digital health tools for the passive monitoring of depression: a systematic review of methods
The number of times each feature (a sleep, b physical activity, c circadian rhythm, d sociability, e location and f phone use) has been reported in all included studies and their association with depression, where these associations are defined as having a below-threshold p-value (“Significant Association”), above-threshold p-value (“Non-Significant Association”), and where statistical methods have been used that do not yield p-values (“Non-p-value”). The graphs also show the number of studies assessing each feature.
