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

Treatment of upper lumbar disc herniation (LDH) with concomitant spinal canal stenosis is challenging. Conventionally, addressing both pathologies endoscopically requires the use of both transforaminal and interlaminar endoscopic systems, which increases surgical invasiveness and procedural complexity. In this study, we adopted a novel technique involving full endoscopic lumbar laminectomy via an interlaminar approach, followed by the application of a specially designed retraction tube. This method allowed safe and minimally invasive removal of central-type upper LDH from both sides without requiring endoscope exchange. In this article, we describe the technical aspects of endoscopic spinal surgery for patients with upper LDH and lumbar spinal canal stenosis.
