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

backgroundAcupuncture is widely practiced and generally considered safe, yet pneumothorax remains a potentially serious adverse event. The clinical characteristics and optimal management of acupuncture‑related pneumothorax have not been fully clarified.

methodsWe retrospectively reviewed patients diagnosed with acupuncture‑related pneumothorax at our institution between 2006 and 2026. Clinical characteristics, management strategies, and outcomes were analyzed. A focused literature review was also conducted using PubMed.

resultsFourteen patients were identified (median age, 48 years; range 30-73; 10 females). Pneumothorax occurred on the right side in 5 patients, on the left in 7, and bilaterally in 2. Most cases were classified as small pneumothorax according to the British Thoracic Society criteria. Six patients were managed conservatively, six underwent ambulatory drainage, and two required chest tube drainage with hospitalization. One patient presented with hemothorax. No recurrence was observed during follow‑up. A literature review identified 11 previously reported cases, including severe and fatal presentations.

conclusionMost cases of acupuncture‑related pneumothorax were mild and successfully managed with conservative or ambulatory treatment. However, severe complications can occur, underscoring the need for clinician awareness and prompt recognition of this potentially serious adverse event.
