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

objectiveWe present such a case of aggressive osteoblastoma of cervical spine. We describe its complicated clinical progression, hoping to shed light on the surgical strategy of this complex tumor.

methodsWe present such a case of aggressive osteoblastoma involving the C6-7 vertebrae. A 25-year-old man was diagnosed as aggressive osteoblastoma of the cervical spine. The lesion encroached upon the radicular foramina and was located adjacent to the canal of the vertebral artery. Preoperative embolization was performed to reduce intraoperative bleeding and to prevent intraoperative injury of the vertebral artery.

resultsA pathologic examination showed osteoblasts suggestive of osteoblastoma. At 2-year follow-up, bony union was achieved, and there was no evidence of recurrence on a CT scan.

conclusionEn bloc total resection for highly vascular osteoblastoma is ideal, but this case shows that piecemeal total resection following preoperative embolization is a surgical option for highly expansive osteoblastoma.
