Laser-Assisted Adjustable Suture Technique in Strabismus Surgery.
Article in Clinical ophthalmology (Auckland, N.Z.), 2020. 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
purposeThe aim of this study was to assess the efficacy and safety of a new technique (argon laser-assisted lysis of the adjustable suture) in strabismus surgery. PATIENTS AND
methodsRecession of lateral rectus muscle was done and was secured to the sclera at the predetermined recession position after suspending it 1.5-2.5 mm farther. A 10-0 nylon suture was placed at the original insertion site, passed under the previously tied muscle suture knot, and tied, advancing the muscle to the new scleral insertion. Postoperatively in the same day of surgery, if the targeted slight overcorrection was not achieved, a topical anesthetic was given, and argon laser was used to cut the nylon suture providing additional muscle recession.
resultsForty-two patients with exotropia were included: 11 children and 31 adults. Eleven (26.2%) patients became orthophoric immediately following muscle recession. Thirty-one (73.8%) patients were undercorrected with a mean residual angle of 8.2±3.3 pd. After laser-assisted release of the suture, 12 (28.6%) patients were orthophoric, with 4 (9.5%) patients still undercorrected and 26 (61.9%) patients overcorrected. By the end of 6 months postoperatively, the overall success rate of the procedure was 88.1%, with only 5 (11.9%) patients with exotropia.
conclusionThe laser-assisted adjustable suture technique had an overall success rate of 88.1% with only 11.9% of the patients showing exotropia. The technique can help achieve successful alignment.
