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
Optic nerve head drusen (ONHD) are typically benign hyaline and calcified concretions located within the optic nerve. Initially asymptomatic, they can increase slowly in size and number over time, and they can cause mechanical stress at the axons of the optic nerve and progressively lead to a loss of the visual field and papillary vascular changes. Here, we reported a rare case of a young patient with bilateral ONHD complicated by a nonarteritic anterior ischemic optic neuropathy (NAION) in the right eye. The aim of this case was to evaluate, using optical coherence tomography angiography (OCTA), the vascular network of the papillary region in both eyes in the presence of this ischemic event associated to ONHD. At OCTA examination, the whole papillary region revealed a general rarefaction of the vascular network, but it turned out to be greater in the right eye affected by nonarteritic anterior ischemic optic neuropathy than in fellow eye. Therefore, these findings demonstrated that ONHD may determine significant ischemic events of the optic nerve and OCTA represents a valid and noninvasive tool in the diagnosis and in the pathogenesis of these rare cases of NAION associated to ONHD in young patients.
