Mechanically Powered Negative Pressure Dressing Enhances Surgical Incision Cosmesis: A Randomized Trial.

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
Background: Cosmetic appearance of incisions remains one of the most important aspects of the patient recovery experience. Despite advances in surgery, scar prevention is the gold standard in improved results. Closed-incision negative pressure wound therapy has shown promise in decreasing surgical site infection and healing time. This study aimed to assess outcomes of primarily closed surgical incisions with mechanically powered negative pressure dressings (MP-NPDs) compared with standard dressings. Methods: This study was a single-center, within-subjects, randomized controlled trial, in which each patient served as both the control and experimental arms. Laparoscopic/robotic port site incisions were randomized to control dressing or MP-NPD. Primary outcomes were cosmetic results at first clinic visit by blinded physicians and nonphysician observers. Results: Forty patients with a total of 80 incisions were included in the analysis. The average scores for scar spread, erythema, dyspigmentation, scar hypertrophy, and overall impression were lower for the MP-NPD wounds. The only individual variable of the Scar Cosmesis Assessment Rating scale, in which there was no difference noted between the 2 groups, was the presence of suture marks. The average total Scar Cosmesis Assessment Rating score was significantly lower (more favorable) for the MP-NPD wounds compared with the control wounds (3.39 ± 3.18 versus 4.79 ± 3.18, respectively; Conclusions: The use of closed-incision negative pressure wound therapy with the application of a novel MP-NPD over surgical incisions resulted in clinical and statistically significant improvement in scar cosmesis in the early/intermediate postoperative period according to both physician and nonphysician observers.
