Prophylactic Incisional Negative Pressure wound therapy (NPWT) for major Amputations (PINTA): protocol for randomized controlled trial of single-use NPWT devices for closed-incision major lower extremity amputations.
Article in BJS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMajor lower extremity amputations are frequently performed for end-stage peripheral arterial disease and progressive diabetic foot complications. Wound complications after amputation affect up to one-third of limbs. The patient cohort undergoing amputation are typically high risk for poor wound healing, often with unmodifiable risk factors in an urgent clinical setting. Incisional negative pressure wound therapy (NPWT) has been shown to reduce wound complications in other high-risk populations. This randomized controlled trial investigates whether prophylactic NPWT reduces wound complications in patients after major amputation compared with standard dry dressings.
methodsThis protocol describes a prospective, multicentre, randomized controlled trial with an internal pilot recruiting patients undergoing major lower extremity amputation for any indication. Limbs will be randomized to receive either a single-use NPWT device on their closed surgical incision or a dry dressing. The primary clinical outcome is the rate of wound complications. Secondary outcomes include reoperation rates, length of hospital stay, cost-effectiveness of NPWT, and patient-reported quality of life. Follow-up will continue to 6 months after surgery. The initial pilot phase has a recruitment target of 96 limbs, whereas an estimated 728 patients will be required to power a definitive trial adequately. DISCUSSION: This trial aims to supplement the existing poor-quality data on this important aspect of care and equip healthcare professionals to make cost-effective decisions regarding postoperative wound management.
