Interventions | 19 participants assigned to the exercise intervention, including:

Contamination of control group: not reported |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | The random location sequence was generated using a table of random numbers |
Allocation concealment (selection bias) | Unclear risk | Whether the treatment assigned was concealed from study personnel and participants was not described |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Owing to the nature of the intervention, it was not possible to conceal allocation to the intervention from the participants |
Blinding of outcome assessment (detection bias) All outcomes | High risk | Allocation to the intervention was not concealed from the study personnel |
Incomplete outcome data (attrition bias) All outcomes | High risk | 44 women were randomly assigned to exercise or control groups and 40 women completed the trial. No information is provided on the 4 women who did not complete the trial |
Selective reporting (reporting bias) | Low risk | There appears to be no selective reporting of outcomes |
Other bias | Low risk | The trial appears to be free of other problems that could put it at a high risk of bias |
