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

objectiveOssification of the posterior longitudinal ligament (OPLL) can lead to compressive myelopathy, which requires surgical intervention. This study aimed to evaluate biomechanical and neurophysiological predictors of postoperative motor (PMD) and sensory deterioration (PSD) in cervical OPLL surgery, with the goal of improving patient prognosis and surgical outcomes.

methodsA retrospective cohort study was conducted on 111 patients with cervical OPLL who underwent surgery with intraoperative neurophysiological monitoring during 5 years in a single institute. The axial size of OPLL, intraoperative motor evoked potential (MEP) changes, and somatosensory evoked potential (SEP) latency prolongation were analyzed using ROC curve and linear path analysis to assess their predictive value for PMD and PSD.

resultsThe axial size of the OPLL at each level demonstrates no significant difference, regardless of changes in SEPs or MEPs, or the presence of postoperative sensory or motor deterioration. Differences in the OPLL occupying area ratio between the C5 and C6 levels (∆OPLL
