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

purposeComplete resection of spinal cord tumors in the thoracic region requires precise preservation of critical vascular structures such as the Adamkiewicz artery. This report highlights the utility of narrow band imaging (NBI) in achieving complete schwannoma removal, while preserving vascular integrity. CASE PRESENTATION: A 72-year-old male presented with left lower extremity weakness persisting for four months. He experienced difficulty cycling uphill and was forced to walk in a forward-bent posture. MRI revealed a dumbbell-shaped mass extending from the intradural space at Th12/L1 into the paravertebral region, resulting in the diagnosis of schwannoma arising from the left Th12 nerve root. Preoperative computed tomography angiography indicated proximity of the Adamkiewicz artery to the tumor. Intraoperatively, NBI facilitated identification and preservation of the Adamkiewicz artery during tumor removal. Postoperatively, the patient's muscle strength improved, and he resumed normal walking without forward bending posture.

conclusionsNBI is a valuable adjunct for visualizing critical vascular structures intraoperatively, ensuring safe and effective tumor resection.
