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

Injury to the recurrent laryngeal nerve (RLN) and its non-recurrent variant (NRLN) remains one of the most significant complications of thyroid and parathyroid surgery. The NRLN is a rare anatomical variation that arises directly from the cervical vagus nerve without looping into the thoracic cavity, most often associated with an aberrant subclavian artery. Identification of this structure is essential to avoid iatrogenic injury, particularly during thyroidectomy. We report the intraoperative neuromonitoring (IONM) identification of an unexpected non-recurrent left inferior laryngeal nerve; emerging directly from the vagus nerve and coursing horizontally towards the larynx. This case emphasizes the importance of IONM, surgical awareness of anatomical variation to prevent RLN and NRLN injury, and ensuring optimal postoperative laryngeal function.
