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

Patellar dislocations commonly occur in young adults and often reduce spontaneously or with closed reduction in the emergency department. However, traumatic patellar dislocations in older adults pose unique challenges, often complicated by degenerative osteophytes that hinder standard closed reduction methods. When closed reduction proves ineffective, patients may necessitate arthroscopic or open surgical intervention. This case report details the experience of a 60-year-old man with a traumatic patellar dislocation resistant to standard closed reduction methods, attributed to impaction of the patella against a lateral femoral condyle osteophyte. We present a novel technique for addressing irreducible patellar dislocations through closed reduction, which has yet to be documented in existing literature.
