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

Primary malignant giant cell tumor of bone (PMGCTB), which is usually confirmed to contain a high-grade sarcomatous component at the time of initial diagnosis, accounts for 1.6% of giant cell tumors of bone (GCTB). PMGCTB usually occurs in the epiphysis of long bones, which is similar to GCTB, and only 1.4-9.4% of GCTB occurs in the spine. PMGCTB in the spine is extremely rare. Herein, we present the case of a 46-year-old man who came to the hospital seeking medical help for lumbosacral pain. Computed tomography (CT) was performed because the clinician suspected that the patient had a herniated disk, and the results showed that the fifth lumbar vertebrae to the second sacral vertebrae showed bone destruction, accompanied by soft tissue tumors near the vertebrae, some of which protruded into the spinal canal and sacral canal. Magnetic resonance imaging (MRI) revealed that the lesion demonstrates an isointense signal on T1-weighted imaging (T1WI), a mixed hyperintense signal on T2-weighted imaging (T2WI), and obvious enhancement on contrast-enhanced T1WI.
