Summary of findings 4. NPWT combined with internet‐plus home care compared with standard care.

Population: adults with pressure ulcers Setting: hospitals and home‐based care Intervention: NPWT combined with internet‐plus home care Comparison: standard care

The proportion of pressure ulcers healed				60 (1 RCT)		The author only reported the proportion of effective treatment (the wound is completely covered with fresh granulation tissue), which we did not include in the analysis.
Time to complete wound healing	This outcome was not reported for this comparison.
Adverse events	This outcome was not reported for this comparison.

CI: Confidence interval; NPWT: negative pressure wound therapy; RCT: randomised controlled trial

GRADE Working Group grades of evidence
High certainty: we are very confident that the true effect lies close to that of the estimate of the effect.
Moderate certainty: we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different.
Low certainty: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect.
Very low certainty: we have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of the effect.
