Outcomes of Thin Groin Flaps for Hand and Finger Reconstruction: A Mixed Retrospective-Prospective Study.
Article in Cureus, 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 Reconstruction of soft tissue defects in the hand and fingers remains challenging, particularly in complex injuries. The thin groin flap, a pedicled flap technique, offers a reliable option for coverage with acceptable functional and aesthetic outcomes. Objective The objective of the study is to evaluate the clinical and functional outcomes of thin groin flap reconstruction for hand defects. Methods This was a mixed retrospective-prospective study conducted in government and private hospitals in Sana'a, Yemen (Typical Police Hospital and Elite Hospital), which have reconstructive surgery units from January 2021 to December 2024. Outcomes assessed included flap healing time, operation duration, Disabilities of the Arm, Shoulder, and Hand (DASH) scores at one month, complication rates, and patient satisfaction. A subgroup analysis evaluated the impact of using magnification loupes during surgery. Results This study involved 25 patients; the median age was 27.0 years (interquartile range (IQR) 22.0-40.0) with a slight male predominance (14, 56.0%). Primary causes of injury were non-gunshot trauma (10, 40.0%), burns (10, 40.0%), and high-energy gunshot injuries (4, 16.0%). The median defect size was 7.0 cm² (IQR 6.0-7.0), and the median time from injury to surgery was 7.0 days (IQR 5.0-16.0). Surgical magnification loupes were used in 22 (88.0%) of procedures. A complete flap survival rate of 24 (96.0%) was achieved, with an overall success rate of 20 (80.0%). Functional outcomes, assessed by the DASH score, were generally favorable (median 10.0, IQR 5.0-25.0). Surgical magnification loupes significantly improved outcomes, reducing complication rates (9.1% (n = 2) vs. 100.0% (n = 3) in the no-loupe group (Fisher's exact test, p = 0.028)), improving functional scores (median DASH 10.0 vs. 50.0 (Mann-Whitney U = 0.0, p = 0.018)), and shortening hospital stays (median 4.5 days vs. 15.0 days; p = 0.004). Predictors of poorer functional outcomes included gunshot wounds, associated injuries, longer time from injury to surgery, and larger defect size. Conclusion The study concludes that thin groin flaps are a reliable option for hand reconstruction, with surgical magnification significantly enhancing outcomes and patient recovery.
