High risk |
Self report using CES‐D score, so not blind |
| Incomplete outcome data (attrition bias)

High risk |
59 randomised, 7/28 in jogging group not available at follow‐up, 3/31 in control group not available for follow‐up; leaving data from 49 to be analysed |
| Selective reporting (reporting bias) |
Unclear risk |
All prespecified outcome measures seem to have been reported, but no protocol |
