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

The trigone of the lateral ventricle is surrounded by important white matter fibers, making it difficult to approach. White matter fibers, such as the superior longitudinal fasciculus, optic radiation, arcuate fasciculus, and inferior fronto-occipital fasciculus, can be clearly depicted by tractography. We propose the safest approach to a trigonal tumor of the lateral ventricle via the superior parietal lobe using tractography. Case: A 49-year-old female presented to our hospital with a chronic headache. Magnetic resonance imaging revealed a meningioma with partial hydrocephalus in the trigone of the left lateral ventricle. After total gross resection, the patient exhibited no cranial nerve, visual, sensorimotor, or language deficits. However, there was a mild acalculia right after surgery, from which the patient made an excellent recovery with no neurological deficits at 3 months after surgery. The endoport-assisted superior parietal lobe trans-sulcus approach using tractography is the safest approach to the trigonal lesion, as it protects the most important white matter fibers around the lateral ventricular trigone.
