Reactive air surfaces may leads to higher time to complete pressure ulcer healing compared with foam surfaces (low certainty).
Electrical stimulation (plus standard care) probably leads to higher proportion of pressure ulcers healed (3 to 12 weeks) compared with sham/no ES (plus standard care) (moderate certainty).
Fatty acid showed no clear difference in pressure ulcer incidence: fatty acid vs olive oil compared with other topical intervention or standard care (low certainty).
It is very uncertain whether active topical agent changes stage 3 pressure ulcer incidence: Conotrane vs placebo compared with placebo/control (very low certainty).
It is very uncertain whether active topical agent changes stage 4 pressure ulcer incidence: Conotrane vs placebo compared with placebo/control (very low certainty).
Silicone dressing may leads to lower pressure ulcer incidence compared with no dressing (low certainty).
It is very uncertain whether silicone dressing changes stage 1 pressure ulcer incidence compared with no dressing (very low certainty).
It is very uncertain whether silicone dressing changes stage 2 pressure ulcer incidence compared with no dressing (very low certainty).
It is very uncertain whether silicone dressing changes stage 4 pressure ulcer incidence compared with no dressing (very low certainty).
It is very uncertain whether silicone dressing changes unstageable pressure ulcer incidence compared with no dressing (very low certainty).
It is very uncertain whether silicone dressing changes deep tissue injury pressure ulcer incidence compared with no dressing (very low certainty).
Fatty acid may leads to lower pressure ulcer incidence: fatty acid vs control compound compared with other topical intervention or standard care (low certainty).
It is very uncertain whether other dressing changes pressure ulcer incidence: polyurethane film vs hydrocolloid dressing compared with control (very low certainty).
It is very uncertain whether other dressing changes pressure ulcer incidence: PPD vs no dressing compared with control (very low certainty).
It is very uncertain whether active topical agent changes pressure ulcer incidence: active lotion vs placebo compared with placebo/control (very low certainty).
It is very uncertain whether active topical agent changes pressure ulcer incidence: Conotrane vs placebo compared with placebo/control (very low certainty).
It is very uncertain whether training, monitoring and observation changes incidence of new pressure ulcers compared with monitoring and observation (very low certainty).
The review found no eligible studies for this question.
It is very uncertain whether training, monitoring and observation changes incidence of new pressure ulcers compared with observation alone (very low certainty).
