Modified KDPIF Technique in Vulvar Reconstruction: An Alternative Approach to the Conventional Technique with Reduced Complications.
Article in International urogynecology journal, 2026. 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
introduction and hypothesisCurrently, the reconstruction of vulvar defects presents a significant challenge for surgeons. The traditional keystone design perforator island flap (KDPIF) has emerged as a mainstream option owing to its reliable blood supply and procedural simplicity. However, postoperative complications such as flap scar contracture and urethral stricture remain prevalent. Therefore, this study introduces a Z-plasty-modified KDPIF technique designed to optimize flap tension distribution and reduce scar contracture while preserving the advantages of traditional KDPIF.
methodsWe conducted a retrospective study including 58 patients between 2016 and 2023. Of these, 28 received traditional KDPIF and 30 received modified KDPIF. Postoperative clinical outcomes were collected for all patients.
resultsIn this study, 30 patients underwent the modified KDPIF procedure, while 28 underwent the traditional KDPIF procedure. The average operation time for the modified KDPIF groups was 81.6 min with a flap size of 98.7 cm
conclusionsThis study establishes that the modified KDPIF technique is a safe and effective surgical approach. It preserves conventional KDPIF benefits while reducing the risk of functional impairments, such as postoperative urethral/vaginal stenosis, and alleviating postoperative scar complications.
