Borges 2014.

Methods	Randomised parallel‐group trial
Participants	29 participants with COPD (CG: n = 14, mean age 68 years, 71% males, mean FEV1 39% predicted; IG: n = 15, mean age 64 years, 53% male, mean FEV1 42% predicted) admitted to the hospital for treatment of COPD exacerbation
Interventions	Rehabilitation: exercise training started on third day of hospitalisation, inpatient pulmonary rehabilitation (completed 5.6 sessions on average) with whole‐body resistance training for upper and lower limbs (session every morning with free weights in 2 sets of 8 repetitions). Completion rate of pulmonary rehabilitation: 95%. Follow‐up: 1 month Usual care: Participants received normative daily care, including chest physiotherapy, non‐invasive ventilation if needed and verbal instructions to carry on with their normative daily physical activities. Participants did not receive an exercise programme or a recommendation to exercise after hospital discharge. Follow‐up: 1 month
Outcomes	SGRQ, 6MWD
Notes	Pulmonary rehabilitation programme was considered not extensive (downgraded by ‐2 for < 10 exercise training sessions and by ‐1 for strength training only). Financial support was provided by the Sao Paulo Research Foundation (Grant no. 2007/51‐354‐7) and the Brazilian Scientific Foundation (Grant no. 305987/2010‐0). Clinical trial identifier: NCT01786928
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated randomisation
Allocation concealment (selection bias)	Low risk	"Allocation was concealed in sequentially numbered, sealed, opaque envelopes"
Blinding (performance bias and detection bias) Hospital admission	Unclear risk	Information not available from trial report
Blinding (performance bias and detection bias) Health‐related quality of life	High risk	Information not available from trial report. Although unavoidable by definition, lack of blinding may affect outcome.
Blinding (performance bias and detection bias) Mortality	Unclear risk	Information not available from trial report
Blinding (performance bias and detection bias) Walk test	Low risk	"Evaluation[s] were performed by a blinded evaluator."
Incomplete outcome data (attrition bias) All outcomes	Low risk	Losses to follow‐up are detailed for both groups, and the final number of participants is balanced between comparison groups.
Selective reporting (reporting bias)	Low risk	Outcome reporting is sufficiently complete and transparent. Clinical trial registration number is not reported.
Other bias	Low risk	No indication of other biases
