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

caseAn 86-year-old woman suffered from dropped head syndrome (DHS). As she was not willing to undergo fusion surgery, we proposed a novel nuchal ligament reconstruction surgery, which is not a direct correction of the malalignment but rather a recovery of the function of extensor muscles under local anesthesia. Twelve months after surgery, the patient remains satisfied and is able to maintain a horizontal gaze.

conclusionThis is the first report regarding a less invasive nuchal ligament reconstruction surgery successfully performed for DHS.
