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
backgroundThis study aimed to investigate the early clinical efficacy of using a "guiding rod" simplified positioning technique combined with percutaneous endoscopic visual trephine for the 1-stage treatment of L4/L5 and L5/S1 lumbar disc herniations (LDHs) using transforaminal and interlaminar approaches.
methodsA retrospective analysis was conducted using the clinical data of 22 patients with concurrent L4/L5 and L5/S1 LDHs who underwent percutaneous endoscopic transforaminal discectomy at the L4/L5 level and percutaneous endoscopic interlaminar discectomy at the L5/S1 treatment by using the "guiding rod" simplified position in combination with percutaneous endoscopic visual trephine in our hospital's orthopedic department from January 2022 to February 2024.
resultsAll procedures were completed without complications. The total number of C-arm fluoroscopies was 7.18 ± 1.30. The visual trephine was used for 3.82 ± 1.76 minutes for foraminoplasty and 7.11 ± 3.91 minutes for laminoplasty. The mean operative times were 48.72 ± 11.43 minutes for the lateral approach and 50.37 ± 12.31 minutes for the posterior approach. Postoperative visual analog scale scores for low back and leg pain, Japanese Orthopedic Association scores, and Oswestry Disability Index scores improved significantly compared with preoperative levels (
conclusionsThis technique offers a safe, minimally invasive, and efficient option for treating dual-segment LDH. CLINICAL RELEVANCE: Advanced techniques in percutaneous endoscopic lumbar discectomy. LEVEL OF EVIDENCE: 4:
