The Scar-suppressing Efficiency of Three Sutures with Different Degradation Rates: A Prospective Split-Scar Study.
Article in Aesthetic plastic surgery, 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
backgroundOur previous study demonstrated that prolonged tension reduction results in satisfactory scar suppression during modified intradermal suturing. The type of suture used in intradermal sutures is crucial for tension preservation, wherein suture degradation results in tension reduction. However, evidence revealing the optimal suture to confront local tension for a prolonged period of time is lacking.
objectiveTo compare the aesthetic outcomes associated with three sutures: polyglactin acid and polydioxanone, which are absorbable sutures with tension-maintaining times of 1 and 3 months, respectively, and the nonabsorbable suture polyester.
methodsWe evenly divided a hypogastric incision into three segments before randomly stitching them with three different sutures. After 1, 3 and 6 months, the aesthetic outcomes of the scars brought by each suture were evaluated by scar assessment scales.
resultsPolyglactin acid had the worst aesthetic outcome at 1, 3 and 6 months. Polydioxanone and polyester had similar aesthetic outcomes at 1 and 3 months. However, at 6 months, polyester showed unsatisfying scar inhibition compared to that of polydioxanone. To explore the underlying mechanism, we repeated the above process in mice and found enhanced inflammation in tissues stitched using polyester. The inflammation neutralized the anti-scarring efficiency of reduced tension.
conclusionOur study revealed that prolonged reduction in local tension plays an important role in inhibiting scarring, and the ability of sutures to induce local inflammation cannot be ignored.
