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

Osteoid osteoma (OO) is a benign osteoblastic tumor characterized by nocturnal pain that responds well to non-steroidal anti-inflammatory drugs. This condition commonly affects adolescents and young adults, and patients between 5 and 24 years of age account for 85% of all OO cases; it occurs very rarely in patients under 5 years old. Tumors often occur in the cortical bone in the diaphysis and metaphysis of the appendicular skeleton and are more common in the lower extremities than upper extremities. Here, we present an extremely rare case of intramedullary OO that arose in the proximal metaphysis of the humerus in a 2-year-old boy, which mimicked subacute osteomyelitis on imaging studies. We also conducted a retrospective literature review and found that the intramedullary location was fairly common in very young patients (<6 years old) with OO.
