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
purposeCervical myelopathy with rigid kyphosis often requires multilevel decompression and realignment. Although 540° surgery-posterior decompression with screw fixation, anterior decompression and fusion, and posterior rod connection-can achieve adequate neural decompression and sagittal correction, it involves substantial surgical burden. This study compared vertebral body sliding osteotomy (VBSO), an anterior-based technique, with 540° surgery for multilevel cervical myelopathy with rigid kyphosis.
methodsA retrospective cohort of 57 patients treated between 2015 and 2022 was analyzed, including 38 who underwent VBSO and 19 who underwent 540° surgery. All patients required fusion across three or more levels and had a minimum of two years of follow-up. Selective ACDF was added to VBSO when pathology extended across disc spaces. Clinical outcomes included Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), and Visual Analog Scale (VAS) for neck pain. Radiological parameters included C2-7 lordosis, segmental lordosis, and canal occupying ratio. Operative time, estimated blood loss (EBL), and complications were also evaluated.
resultsImprovements in JOA, NDI, and neck pain VAS were comparable between groups (all p > 0.05). Postoperative C2-7 lordosis was similarly restored, and complication rates showed no significant differences. VBSO demonstrated a markedly shorter operative time (262.1 vs. 440.4 minutes, p < 0.001) and lower EBL (100.4 vs. 272.2 mL, p < 0.001).
conclusionsVBSO achieved clinical and radiological improvement with reduced surgical burden relative to 540° surgery. These findings suggest that VBSO may be considered a reasonable and efficient alternative for treating cervical myelopathy with rigid kyphosis.
