RETROSPECTIVE ANALYSIS OF THE IMPACT OF NEGATIVE PRESSURE WOUND THERAPY ON COMPLICATIONS OF DELAYED COVERAGE OF IIIB EXPOSED TIBIAL FRACTURES.

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
Objective: To evaluate whether NPWT in delayed coverage of Gustilo-Anderson Type IIIB open tibial fractures reduces the complication rate, including deep infection, nonunion, and amputation. Methods: Retrospective case series including patients with Gustilo-Anderson Type IIIB open tibial shaft fractures treated between January 2014 and December 2017 with NPWT. The outcome measures were incidence of deep infection, nonunion, and amputation. Analysis of time to coverage (within 7 days vs. after 7 days) and type of soft tissue coverage. Results: 26 patients with open tibial shaft fractures, predominantly male (96.2%), mean age 33.4 ± 13.9 years. Seven patients (26.9%) received coverage within 7 days; 19 patients (73.1%) received delayed coverage. The flap types were Myocutaneous (42.3%), microsurgical (34.6%), fasciocutaneous (23.1%). The overall infection rate was 50%, no significant difference between early (57.1%) and delayed (47.4%) coverage groups (p > 0.999). No amputations in the early coverage group; 2 (10.5%) in the delayed coverage group. Nonunion rates were 42.9% (early) and 36.8% (delayed). Overall complication rate: 85.7% (early) vs. 57.9% (delayed) (p = 0.357). Conclusion: NPWT may exert a protective effect in cases of delayed coverage by isolating the wound and promoting healing.
