Safety thresholds for removing and preserving corneal tissue in small-incision lenticule extraction: A PRISMA-Compliant study.
Review in Advances in ophthalmology practice and research. 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: Ranges of corneal tissue removal and residual stroma are the most essential safety consideration for corneal refractive procedures and directly determine the eligibility of candidates who may benefit from surgery. Small-incision lenticule extraction (SMILE), a laser procedure, has been performed for more than 10 years with well-established efficacy and predictability. However, determining the optimal safety limit for corneal tissue removal is still a challenge, perplexing surgeons. Main text: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Six electronic databases (PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, and Wanfang Data) were searched. Corneal removal and remaining thresholds were mainly quantified by maximum lenticule thickness (MLT), residual stromal thickness (RST), and percentage of tissue alteration (PTA Results: Twenty-five studies (3247 eyes) were included. Corneal stability post-SMILE declined with increased tissue removal and decreased residual stroma. From a corneal biomechanical perspective, postoperative weakening of corneal biomechanical strength was more pronounced when RST was <280 μm or PTA Conclusions: Until more specific metrics are validated, RST (280 μm) and PTA
