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

purposeWe aimed to analyze the changes in the visual cortex of a ferret model of ocular hypertension (OH) using cytochrome oxidase (CO) staining. STUDY

designExperimental.

methodsOH was induced in 9 ferrets by means of injection of cultured conjunctival cells into the anterior chamber of the right eye. Three ferrets were used as the controls. CO staining was performed to assess the metabolic intensity at the II-III and IVC layers of the visual cortex.

resultsThe intensities of CO staining in the right and left II-III layers of the primary visual cortex (V1) in the OH ferrets were 39.8 ± 10.3 and 41.9 ± 9.2 arbitrary units, respectively. In the control ferrets, the intensity was 88.1 ± 8.1 arbitrary units. The intensity of CO staining of the II-III layers obtained from the OH eyes was significantly lower than that from the control eyes (unpaired t test, P < .01). The intensities of CO staining in the right and left IVC layers of V1 in the OH ferrets were 60.3 ± 12.8 and 60.0 ± 13.5 arbitrary units, respectively. In the control ferrets, the intensity was 111.4 ± 9.6 arbitrary units. The CO staining intensity of the IVC layer obtained from the OH eyes was significantly lower than that from the control eyes (unpaired t test, P < .01).

conclusionThe CO staining intensity was reduced in the visual cortex from OH eyes. This study revealed that OH causes metabolic change in the visual cortex.
