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

Anatomical variations of the median nerve (MN) are very common. They may contribute to MN pathology. In addition, if not recognized, they may present a significant risk of iatrogenic nerve injury during surgical interventions. We describe two cases of an unusual bifid MN course with the ulnar division penetrating the flexor digitorum superficialis muscle. Both cases were identified during ultrasound (US) examination of the MN. US is an excellent tool that should be routinely used not only in the diagnosis of MN pathology but also to identify its anatomical variations prior to surgical procedures.
