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
backgroundEncircling scleral buckling is a surgical intervention employed for the purpose of visual restoration in individuals diagnosed with rhegmatogenous retinal detachment (RRD). While this particular approach is not commonly used for the purpose of enhancing accommodation, it has garnered attention in various studies. This research aimed to objectively measure accommodation changes using the iTrace device in patients with RRD who have undergone encircling scleral buckling surgery.
methodThis pilot prospective cohort study included 40 eyes from 20 patients with RRD who underwent encircling scleral buckling surgery in one eye. The surgical group included 20 RRD eyes and the non-exposure group included 20 healthy eyes. The objective aberrometry was performed by directing a light beam at a 6-m and 20-cm distant using the iTrace. We assessed post-surgical accommodation changes within two groups using the Wilcoxon signed-rank test, quantified clinically relevant changes with the mean difference (MD), and evaluated change magnitude with the standardized mean difference (Hedges' g).
resultsThe average age of the patients was 33.9 ± 8 years, with 12 males and 8 females. Baseline accommodation for the non-operated eye measured 2.76 diopters at 20 cm and 1.37 diopters at 50 cm. At 20 cm, the non-operated and operated eyes showed mean accommodation changes of 0.2 diopters (p = 0.123) and 0.01 diopters (p = 0.949), respectively. At 50 cm, the non-operated eye changed by 0.12 diopters (p = 0.292) while the operated eye decreased by - 0.01 diopters (p = 0.930). Overall, minor postoperative accommodation changes were observed, with no significant differences detected.
conclusionEncircling scleral buckling in RRD patients shows no significant changes observed postoperatively in either operated or non-operated eyes and the 98.75% CI suggests any potential benefit is likely too small to be clinically meaningful.
