High correlation of scotopic and photopic electroretinogram components with severity of central retinal artery occlusion.
Article in Clinical ophthalmology (Auckland, N.Z.), 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
purposeThe aim of this study was to determine whether a significant correlation exists between the scotopic and photopic components of electroretinograms (ERGs) and the degree of circulation disturbances caused by a central retinal artery occlusion (CRAO).
designObservational clinical study.
participantsSixteen patients with a CRAO (16 eyes).
methodsThe circulatory disturbance in eyes with CRAO was graded as mild (group 1) when the arm-to-retina transmission time was <30 sec and severe (group 2) when the arm-to-retina transmission time was ≥30 sec. Scotopic and photopic ERG components in eyes with CRAO were compared with those in healthy fellow eyes with respect to the degree of circulation disturbance.
resultsThe scotopic and photopic b-waves were significantly reduced only in group 2, whereas the amplitudes of the photopic negative response (PhNR) of the photopic cone ERGs were significantly reduced in both groups. The amplitudes of each ERG component, except for the a-wave of the mixed rod-cone ERG, were significantly smaller in group 2 than in group 1.
conclusionsThe PhNR was reduced even in group 1 with minimal circulatory disturbance and thus may be a good functional indicator.
