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
backgroundTo compare visual, refractive, and anatomical outcomes of lens extraction with Cionni ring and in-the-bag intraocular lens (IOL) implantation and Yamane intrascleral fixation in pediatric Marfan patients with lens subluxation.
methodsThis retrospective cohort study included 21 patients (29 eyes) who underwent IOL implantation for ectopia lentis due to Marfan syndrome. Surgical techniques included Yamane sutureless scleral fixation and scleral fixation with Cionni capsular rings. Postoperative outcomes assessed were corrected visual acuity (CVA) in decimal, spherical equivalent (SE) refraction, lenticular astigmatism, IOL tilt/decentration, endothelial cell count, and complications.
resultsSixteen eyes were included in the Yamane group and 13 in the Cionni group. Both groups demonstrated a significant improvement in CVA compared to preoperative values (Yamane, p = 0.001; Cionni p = 0.002). A significant postoperative improvement in SE was also noted in Yamane group (p = 0.009). The degree of IOL tilt was comparable between groups (Yamane, 0.80 ± 0.27°; Cionni, 1.33 ± 0.93°; p = 0.240); however, IOL decentration occurred in 4 eyes in the Cionni group and 3 eyes in the Yamane group. No major intraoperative complications were reported. Among the postoperative complications, retinal pathology and glaucoma each occurred in 2 patients in the Yamane group. The median postoperative follow-up duration was 16.6 (min-max: 7–34 months) months in the Modified Yamane group and 22.6(min-max: 8–35 months) months in the Cionni group (p = 0.232).
conclusionsIn patients with lens subluxation secondary to Marfan syndrome, IOL implantation using either the Yamane technique or the Cionni ring yields favorable anatomical and functional outcomes. These methods may be considered viable options following thorough preoperative assessment, particularly when the risk of intraoperative and postoperative complications is deemed low.
