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

Nonarteritic ischemic optic neuropathy (NAION) is believed to be an ischemic insult to the optic nerve head and is one of the most common acute optic neuropathies of adulthood. Prevention of NAION in the fellow eye has not yet been accomplished. Optical coherence tomography angiography (OCTA) is a new and emerging non-invasive technology that provides microvascular information that complements the structural data. This prospective study is aimed to fill the lacunae in data that is available in the Indian population. We included 36 patients with NAION, their 36 fellow eyes and 37 healthy controls. The peripapillary perfusion index, peripapillary flux, peripapillary retinal nerve fibre layer (RNFL) thickness values and disc volumes of eyes were evaluated. The NAION eyes had lower peripapillary perfusion index, flux and RNFL thickness values in all sectors compared with both the fellow and the healthy control eyes (
