1 · What the graph read from it

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.

2 · The registry

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

Objective: To evaluate the safety and efficacy of a long-shaft vitrectomy probe in highly myopic eyes undergoing pars plana vitrectomy. Design: A randomized controlled trial. Subjects: Highly myopic eyes (axial length [AL] >26 mm) with epiretinal membrane (ERM), myopic tractional maculopathy, and retinal detachment. Methods: The enrolled eyes were randomly assigned to a study group (UltraVit 25 Ga, 31.75 mm, Alcon) and a control group (UltraVit 25 Ga+, 27 mm, Alcon). Stratified randomization was performed to balance the proportion of eyes with AL >28 mm between groups. Main Outcome Measures: Trocar removal rate and core vitrectomy time were assessed as primary outcomes, and instrument bending as a secondary outcome. Anatomical and visual outcomes and complications were documented for 6 months. Subgroup analysis was performed to compare the eyes with AL >28 mm to those without. Results: We included 86 patients with a mean age of 60.7 ± 9.6 years and an AL of 29.15 ± 2.14 mm. Two groups had comparable core vitrectomy times (-0.5 minutes, Conclusions: The long-shaft vitrectomy probe is safe and efficient, especially in highly myopic eyes with AL >28 mm, despite a higher instrument bending rate. It provides improved access to the posterior pole, allowing for delicate removal of adherent cortical vitreous and trimming of ILM flaps. Addressing increased instrument bending due to the sleeveless design is important for future design.
