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

purposeTo examine the relationship between posterior vitreous changes and retinal detachment (RD) associated with acute retinal necrosis (ARN). STUDY

designRetrospective, consecutive case study.

methodsThis study evaluated the clinical findings for 32 eyes of 29 patients (12 women, 17 men) diagnosed with ARN, with the posterior vitreous condition monitored by swept-source optical coherence tomography (SS-OCT). The causative virus, incidence of RD, and relationship between the development of RD and final visual acuity were investigated. Patients were checked for posterior vitreous detachment (PVD) from the initial visit to the last SS-OCT observation.

resultsVaricella-zoster virus caused 67% of the ARN cases, with RD developing in 66% of the cases, and proliferative vitreoretinopathy (PVR) in 90% at onset or at recurrence. Silicone oil could not be removed in 38% of the cases with RD. Final best-corrected visual acuity was significantly worse in the RD (+) group than in the RD (-) group (median logMAR 1.02 vs. 0.16, p = 0.04). PVD occurred in 20 of 21 eyes without PVD at the initial examination, with 18 of these 20 eyes developing RD (90%). PVD occurred at an average of 45.8 ± 32.1 days after the initial examination, with 85% of the cases developing PVD within 3 months.

conclusionsThe visual prognosis of ARN complicated by RD is poor. PVD is involved in the development of RD and is often associated with PVR, which itself is refractory.
