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
BACKGROUND Thoracic ossification of ligamentum flavum (TOLF) is a common pathological change of the thoracic ligamentum flavum. Identifying the risk factors for poor prognosis is critical for choosing suitable surgical methods. MATERIAL AND METHODS A total of 64 patients with TOLF after laminectomy were reviewed between January 2010 and April 2018 at the Department of Spine Surgery of the Third Hospital of Hebei Medical University. The Japanese Orthopaedic Association (JOA) scale was used to evaluate the neurological function of patients. According to the average JOA improvement rate, the patients were divided into the good prognosis group (Group GP) and the poor prognosis group (Group PP). Multivariate logistic regression analysis was used to identify the risk factors for poor outcomes. RESULTS The average JOA improvement rate was 53.04±24.29%. Group GP comprised 33 patients, while Group PP comprised 31 patients. Duration of preoperative symptoms (P=0.005), intramedullary high signal intensity (P=0.001), dural ossification rate (P=0.002), and sagittal configuration of ossification (P=0.012) were significantly higher in Group PP than in Group GP. Multivariate logistic analysis showed that duration of preoperative symptoms (P=0.022), intramedullary high signal intensity (P=0.010), dural ossification (P=0.007) and sagittal configuration of ossification (P=0.029) were risk factors for poor outcomes of TOLF after laminectomy. CONCLUSIONS After surgical treatment of TOLF, the symptoms of some patients either recovered slowly or did not recover. Longer than 17 months of preoperative symptoms, intramedullary high signal intensity, dural ossification, and sagittal configuration of ossification were the risk factors for poor outcomes of TOLF after laminectomy.
