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

backgroundWhen pain caused by lumbar disc herniation (LDH) is not relieved after 4 to 6 weeks of conservative treatment, surgery is recommended. Open microdiscectomy is a standard surgical technique, but surgical endoscopy enables endoscopic lumbar surgery with clinical outcomes similar to those of standard microdiscectomy. Endoscopic lumbar discectomy is largely divided into transforaminal endoscopic lumbar discectomy (TELD) and interlaminar endoscopic lumbar discectomy (IELD). TELD was introduced about 10 years earlier than IELD and seems to be more popular than IELD.

objectiveThe present article reviews the surgical technique, indications, and outcomes of IELD. Although much is still unknown, potential future perspectives are reviewed. SUMMARY: Although improved surgical techniques enable TELD to be versatile, IELD is still specifically beneficial for patients with highly migrated LDH and a high iliac crest. There is a large body of literature indicating favorable outcomes with both TELD and IELD. Currently, the selection of TELD or IELD is at the discretion of the surgeon, but the IELD surgical technique is useful for further applying endoscopic lumbar surgery for lumbar decompression or lumbar interbody fusion. The techniques can be assisted by advanced technologies such as artificial intelligence, surgical robots, and artificial reality, and a precise and systematic approach to decision-making and surgical techniques is required to combine these technologies effectively.
