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

STUDY

designA review of the literature and three case reports.

objectivesPrimary spinal melanoma (PSM) of extramedullary origin is a rare malignant condition with limited current literature in regards to its clinical course, magnetic resonance imaging (MRI) findings, treatment strategies and prognosis. We reported here three cases of PSM of extramedullary origin.

settingChina, Guangzhou.

methodsWe report three cases of PSM of extramedullary origin. The clinical and radiological findings of these cases were retrospectively analyzed.

resultsThe three cases were all of males aged 39, 47 and 76 years, respectively. The duration of their symptoms was 3 weeks, 2 months and 11 months respectively. The extramedullary tumors were all well-defined solitary tumors and were located at C4-5, L2-3 and T9-10, respectively. In one case, involvement of the intervertebral foramen was found. Preoperative MRI showed hyperintense T1W signals and hypointense T2W signals in all three cases and all tumors were clinically misdiagnosed as schwannomas. The patients received total or subtotal resection surgery without radiotherapy or chemotherapy. Patients were alive at 18 months, 27 months and 36 months postoperative follow-up, respectively.

conclusionPSM of extramedullary origin is a rare malignant tumor that shows characteristic findings on MRI. Surgical resection is the preferred treatment strategy.
