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.
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
Objective: To investigate the risk factors of facet joint excessive resection and its influence on effectiveness after the treatment of degenerative lumbar diseases under large-channel endoscope. Methods: The clinical data of 212 patients with degenerative lumbar diseases treated with large-channel spinal endoscopic technology between June 2022 and June 2024 were retrospectively analyzed. Among them, 120 were male and 92 were female. The age ranged from 18 to 85 years, with an average of 54 years. According to the facet joint resection rate measured by CT after operation, the patients were divided into preservation group (facet joint preservation rate≥50%) and excessive resection group (facet joint preservation rate<50%). Visual analogue scale (VAS) score for low back and leg pain, Oswestry disability index (ODI), and Japanese Orthopaedic Association (JOA) scores were used to evaluate the improvement of pain and function before operation, at 1 month after operation, and at last follow-up, and the modified MacNab criteria were used to evaluate the effectiveness at last follow-up. The occurrence of lumbar instability was observed during follow-up. Univariate analysis was performed on variables including gender, age, body mass index, responsible segment, surgical side, whether over-top decompression was performed, whether presence of lateral recess stenosis, whether presence of intervertebral disc calcification, whether presence of lumbosacral transitional vertebrae, whether presence of facet joint hyperplasia, and imaging parameters [facet joint angle (FJA), laminar lateral-oblique angle, maximum width between the medial and lateral margins of the superior articular facet on axial CT (d Results: All patients underwent operative procedures successfully, and all incisions healed by first intention. No complication such as vascular and nerve injury, infection, and spinal cord hypertension-like syndrome occurred. There were 55 patients enrolled in the excessive resection group, and 157 patients in the preservation group. All patients were followed up 12-36 months, with a mean of 23.5 months. There was no significant difference in low back pain VAS score, leg pain VAS score, ODI, and JOA score between the two groups preoperatively ( Conclusion: The incidence of excessive resection of facet joint in lumbar degenerative diseases treated by large-channel endoscopic depression reached 25.94% (55/212), and excessive resection of facet joint affects the recovery of lumbar pain and function in the short term after operation. Female patients, lateral recess stenosis, and FJA (≤45°), d
