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
introductionThe aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (PCIOLs) and to demonstrate a method for validating the lens position.
methodsRetrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).
resultsA total of 18 eyes were included. The mean duration of follow-up was 140 days (range 23-659), and the median time from PCIOL implantation to fixation was 8.5 years (IQR 6.25-10.75). All patients had ocular comorbidities, mainly glaucoma (n = 6) and pseudoexfoliation syndrome (n = 5). Best corrected visual acuity improved from a median of 6/30 (0.7 logMAR) to a median of 6/12 (0.35 logMAR) (p = 0.06); postoperative astigmatism measured 0.91 ± 2.19 diopters. UBM demonstrated well-balanced PCIOL fixation with no difference between the horizontal and vertical tilt measurements (p = 0.84; p = 0.94; p = 0.62; p = 0.085). The fixated PCIOL showed <10% decentration with reference to the visual axis. There was a high negative correlation between BCVA improvement and residual lens tilt (r = -0.76, p = 0.037). Postoperative complications included transient ocular hypertension (n = 3), corneal decompensation with subsequent keratoplasty (n = 3), temporary hypotony (n = 2), cystoid macular edema (n = 1), suture exposure (n = 1), and endophthalmitis (n = 1).
conclusionsSubluxated PCIOLs are amenable to treatment with minimally invasive fixation using Gore-Tex suture with good anatomic outcomes. UBM image analysis may serve as a valuable method for assessing PCIOL position following scleral fixation.
