A Randomised Controlled Trial of Early Vitrectomy and Intravitreal Antibiotics for Post-operative Exogenous Endophthalmitis (EVIAN study): study protocol for a feasibility trial.
Article in NIHR open research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Postoperative bacterial endophthalmitis is an infection of the eye's internal tissues resulting from an intraocular procedure. The condition is uncommon but can cause severe and irreversible impairment of sight. Standard management involves administration of antibiotics with or without subsequent removal of the infected vitreous gel by vitrectomy surgery. Surgical intervention is typically reserved for infections that persist despite a period of medical management alone. We aim to determine whether outcomes can be improved by performing surgery without delay. To explore the feasibility of a definitive randomised controlled trial and to determine the number of participants required, we will conduct a multicentre feasibility trial. This trial will include 40 affected individuals, allocated randomly to either standard of care, being intravitreal antibiotic administration alone, or to early vitrectomy surgery in addition to antibiotic administration. We will determine the feasibility and size of a definitive trial by evaluating the participants and the outcomes for their sight. Research Ethics Committee approval (REC 20/WM/0264). Here we describe the trial protocol.
