Article in North American Spine Society journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo evaluate a novel effective procedure utilizing three-column reconstruction via a posterior approach with a technique that utilizes an arthroscope to visualize the anterior surface of the dura during decompression.
methodsA Prospective Study. 80 Osteoporotic vertebral burst fracture patients with similar demographic data managed by three-column reconstruction through single posterior approach surgery: Pedicle screw fixation, Corpectomy, Arthroscope Assisted Transpedicular Decompression (AATD) and Fusion (Mesh Cage + Bone grafting). Preoperative and postoperative clinical parameters (Visual Analog Score VAS, swestry Disability Index ODI, neurlogy, radiological parameters and surgical variables were recorded analysed.
resultsNo significant differences in demographic data. Significant improvement was noted in VAS (pre-operative, 7.90 ±0.60; final follow-up 2.90 ± 0.54) and ODI (preoperative, 77.10 ± 6.96; final follow-up 21.30 ± 6.70). Neurological improvement was noted in 74 patients (Frankel grade E) while six patients remained non-ambulatory (Frankel grade C). Significant improvement was noted in local kyphosis angle (preoperative, 22.14 ± 2.60; postoperative, 10.40 ± 1.40) with a 10% loss of correction (2.5 ± 0.90) at final follow-up. Implant failure in two patients and proximal junctional failure in two patients managed with revision surgery. No iatrogenic dural or nerve injury.
conclusionsOsteoporotic Burst fracture can be managed with single posterior surgery, three-column reconstruction with mesh cage. It provides a significant improvement in clinical, radiological and functional outcomes. The arthroscope can improve a surgeon's operative field and magnification thereby ensuring complete decompression without injuring the dura or spinal cord.
