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

Botulinum neurotoxin (BoNT) injection into the trapezius muscle is increasingly performed for aesthetic contouring. However, iatrogenic pneumothorax has not been previously documented for this cosmetic indication, despite the inherent anatomical risks. We report a 26-year-old woman who developed immediate severe radiating pain during bilateral trapezius BoNT type A (BoNT-A) injections using a 4.8-cm, 25-gauge needle. During the injection, the patient experienced immediate severe radiating pain, followed by pleuritic chest pain and dyspnea within 30 minutes. Computed tomography confirmed a 30% left pneumothorax, effectively ruling out systemic botulism. Subsequent ultrasound revealed a skin-to-pleura distance of only 2.27 cm at the injection site, highlighting the stark mismatch with the 4.8-cm needle used. The patient was managed conservatively with high-flow oxygen, achieving complete clinical and radiographic resolution within 1 month. This case underscores that pneumothorax is a real risk with blind injection techniques and overly long needles. To minimize harm, practitioners should adhere to anatomically defined safe zones, select conservative needle lengths, and utilize ultrasound assistance when necessary, particularly for thin patients.
