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

A 19-year-old male sea otter (Enhydra lutris) exhibited systemic seizures, declining consciousness, temporary cardiopulmonary arrest, and right-side rotation. The sea otter died approximately one month after its initial seizure. Postmortem magnetic resonance imaging examination revealed a high-intensity region in the left frontal lobe. At necropsy, a gelatinous lesion in the left frontal lobe of the brain was revealed. Histopathologically, the lesion consisted of neoplastic proliferation of round to polyhedral monomorphic cells with a honeycomb growth pattern, small round nuclei, and cytoplasmic halos. The neoplastic cells were immunopositive for oligodendrocyte transcriptional factor-2 (OLIG2) and immunonegative for glial fibrillary acidic protein (GFAP). In this study, we describe the clinical signs and histopathological features of oligodendroglioma, which have rarely been reported in sea otters.
