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

Background: A 34-year-old man presented to our primary care clinic with persistent pain and swelling of the right first metatarsophalangeal joint lasting 3 months. A previous clinic had suspected gout based on hyperuricemia, but urate-lowering therapy was repeatedly withheld because of ongoing inflammation, resulting in prolonged symptoms managed only with nonsteroidal anti-inflammatory drugs. Case Presentation: Ultrasound-guided joint aspiration yielded a dry tap owing to highly viscous chalky material. Point-of-care ultrasound demonstrated diffuse hyperechoic intra-articular deposits and a double contour sign without synovial hypervascularity on color Doppler. Conclusion: This case highlights the diagnostic utility of point-of-care ultrasound in prolonged monoarthritis when invasive aspiration is unsuccessful/contraindicated.
