Chronic unilateral groin pain in a young patient who injects drugs: a case report of needle fragment retentions.
Article in Addiction science & clinical practice, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundSubcutaneously retained needle fragments in people who inject drugs (PWIDs) are a possible cause of local symptoms, most commonly pain and infections. It remains unknown how common retained needle fragments are among PWIDs. CASE PRESENTATION: A young PWID consulted a primary care physician due to chronic left-sided groin pain. The patient suspected retention of a broken needle as the cause. She had used a re-used needle 3 months earlier. A plain pelvic radiograph confirmed a needle fragment in the patient's left groin, and a computed tomography scan located it adjacent to the femoral artery and vein. Another asymptomatic needle fragment was found in the right groin.
conclusionNeedle fragments are possible causes of local symptoms among PWIDs. The clinical examination presents a potential risk of needlestick injury to the examiner, especially because patients may not be aware of all needle fragments as some are asymptomatic.
