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 In Yemen, traumatic wounds are prevalent, imposing a substantial burden on plastic surgery teams operating within limited-resource settings. Advanced microsurgical reconstruction options are scarce, and expertise in free flap techniques is limited. While local flaps are commonly used for soft tissue reconstruction, there is a need for simpler, effective alternatives with lower complication rates. This study aimed to evaluate the effectiveness and outcomes of the keystone island perforator flap (KIPF) as a viable alternative for soft tissue coverage in resource-challenged facilities. Methods From February 2021 to December 2023, a single surgeon's team in three plastic and reconstructive surgery departments in Sana'a, Yemen, conducted this prospective study, which included 35 patients who underwent KIPF for various soft tissue defects. We assessed patient demographics, intraoperative variables, and postoperative outcomes, including aesthetic outcomes evaluated using the Patient and Observer Scar Assessment Scale (POSAS) at six months postoperatively. We analyzed the factors influencing flap success and complication rates. Results The mean age of patients was 29 ± 11.75 years, with the majority being males, comprising 86% of the sample. Trauma was the leading cause of tissue defects (77.1%), primarily affecting the legs (57.14%) and feet (11.43%). The mean operative time was 73.57 minutes. Complications occurred in 26% of patients, with flap dehiscence being the most common (11.43%). Ninety-seven percent of patients experienced flap survival, and 91.4% experienced complete wound healing within a median of 16 days. Scar assessments at six months postoperatively indicated satisfactory aesthetic outcomes, with scars resembling normal skin. Conclusion The KIPF technique proves to be a reliable and practical option for soft tissue reconstruction in resource-limited settings. Its simplicity, minimal postoperative care needs, and high flap survival rates make it an advantageous alternative to more complex reconstructive techniques. This study supports the adoption of KIPF as a standard approach in similar environments with limited reconstructive surgery capabilities.
