Source of bias: selection bias (randomisation and concealed allocation), performance bias (blinding of participants and personnel), detection bias (blinding of outcome assessment), attrition bias (incomplete outcome data: >20 %), reporting bias (selective reporting) and other source of bias
BC body composition, BP blood pressure, DXA dual energy X-ray absorptiometry, FG fasting glucose, RHR resting heart rate, VO 2max maximal oxygen uptake, + low risk of bias (plausible bias unlikely to seriously alter the results), − high risk of bias (plausible bias that seriously weakens confidence in the results), ? unclear risk of bias (plausible bias that raises some doubt about the results)
