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

This narrative review compares decompression alone and decompression with fixation in the surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) in terms of postoperative progression of ossification. Using published studies, we analyzed ossification size changes at the surgical site and adjacent segments. The results suggest that fixation not only stabilizes the spine but may also suppress the progression of ossification, although neurological outcomes were comparable between decompression with fixation and decompression alone. However, the enlargement of ossification observed at the segments adjacent to the operated levels is occasionally greater in cases treated with decompression with fixation than in those treated with decompression alone. These results may be important in determining the optimal surgical strategy based on OPLL morphology and spinal alignment.
