Reconstruction of the subungual region for tumors of the thumb: Outcomes of the reverse, dorsoulnar flap.
Article in JPRAS open, 2025. 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
Background: For subungual, malignant skin tumors of the thumb, ultimate treatment has mostly been the amputation, a procedure that comes with a significant functional loss. We propose reconstruction of the defect with the reverse, homodigital, dorsoulnar, pedicled (RHDU) flap, if no osseous infiltration is present. Methods: We present the cosmetic and functional results in five patients treated for subungual tumors of the thumb between May 2020 and September 2023. Range of motion in the metacarpo-and interphalangeal joints, the widening angle of the first web, Kapandji score, grip and pinch strength, outcome scores including the disability of the arm, shoulder and hand (DASH) and Michigan Hand Score (MHQ) were assessed at final follow up. Results: Range for follow up was 1-5 years. Function was comparable to the contralateral side. Patient reported outcome showed satisfactory function with an average DASH score of 12.82 and MHQ score of 84.8. The cosmetic result was rated with an average of 90 points on the visual analogue scale for cosmesis. No recurrence of the tumor has been reported in any case. Conclusion: Reconstruction of the defect with a RHDU flap after excision of subungual tumors and proof of no osseous invasion, is a reliable and a promising alternative to an amputation, resulting in satisfactory functional and cosmetic outcomes.
