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

backgroundOssification of the ligamentum flavum (OLF) occurs mostly in adult males, typically in the thoracolumbar spine where it may contribute to neurological deficits. Here we reviewed 68 cases of cervical OLF resulting in progressive quadriparesis.

methodsThe literature on cervical OLF was reviewed between 1962 and 2018 along with the case of an 81-year-old male with progressive quadriparesis attributed to cervical OLF.

resultsMost patients with cervical OLF are Asian, with Caucasians constituting the second most frequently impacted population.

conclusionsCervical OLF is typically reported in the Asian, followed by the Caucasian population, and is most often found in the thoracolumbar spine. Here we presented an 81-year-old male with cervical OLF contributing to quadriparesis.
