Lifting Efficiency of Barbed Sutures for Potential Face Lifting Application: A Parametric Analysis.
Article in Journal of cosmetic dermatology, 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
backgroundAbsorbable barbed sutures have been widely used for minimally invasive facial rejuvenation. However, clinical lifting performance varies due to differences in suture geometry, which remain insufficiently quantified.
objectiveThe study aims to evaluate the effects of barb rotation angle, barb orientation, and pulling speed on the lifting performance and efficiency of the barbed sutures. The goal is to identify the optimized geometric design for facial lifting applications.
methodsThe barbs were fabricated with four rotation angles (30°, 45°, 90°, and 180°) and four orientations (Forward, Reverse, Forward-Reverse, and Reverse-Forward). The fabricated sutures were tested at 10, 50, and 100 mm/min. Maximum lifting and holding displacements and lifting efficiency were quantified. Statistical analysis was conducted using one-way ANOVA with Tukey's post hoc test (p < 0.05).
resultsHigher pulling speed increased maximum lift but reduced efficiency due to slippage. The maximum lift was at 100 mm/min (2.03 ± 0.08 mm), whereas the highest lifting efficiency was at 10 mm/min (42.7%). For the barb rotation angles, the 90° configuration showed the highest lifting efficiency (35.5%) and superior anchor stability (p < 0.05). Regarding the barb orientation, the Forward orientation produced the largest lift (1.72 ± 0.18 mm), while the Forward-Reverse orientation achieved the highest efficiency (35.5%). The optimized Forward-Reverse 90° configuration exhibited improved holding capacity and reduced slippage compared to a commercial barbed suture.
conclusionBarb geometry critically affects the lifting performance of the suture. The Forward-Reverse 90° configuration shows the optimal lifting efficiency and stability, offering clinically relevant guidance for designing next-generation facial lifting sutures.
