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

objectiveTo introduce the concept of 'nerve root as the core' and to investigate the surgical procedure and curative effect of percutaneous translaminar endoscopic discectomy (PTED) surgery in the treatment of different types of lumbar disc herniation (LDH).

methodsThis retrospective study analysed the clinical data from patients with LDH that underwent single-segment PTED surgery. They were divided into three groups based on LDH location: central canal zone group, lateral recess zone group and foraminal/far lateral zone group. Different working cannula placement methods were used for the different types of LDH. All patients were followed for at least 12 months. Clinical and follow-up data were compared between the three groups.

resultsA total of 130 patients were enrolled in the study: 44 (33.8%) in the central canal zone group, 72 (55.4%) in the lateral recess zone group and 14 (10.8%) in the foraminal/far lateral zone group. All three groups of patients achieved good postoperative results. The improvements in leg pain and disability were most marked in the first postoperative month in all three groups.

conclusionPTED achieved adequate decompression for different types of LDH. The concept of 'nerve root as the core' facilitated the accurate placement of the working cannula.
