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

Ochronotic arthropathy is a rare condition found in patients with alkaptonuria that results from the accumulation of ochronotic pigment. We present the case of a 65-year-old woman who presented for medical evaluation due to hip and knee chronic pain. The physical and radiographic findings were compatible with an end-stage hip osteoarthritis and knee osteoarthritis. During total hip arthroplasty it was noticed that the articular capsule and the cartilage of the femoral head were black. In the postoperative period she was diagnosed with alkaptonuria. Later, a total knee arthroplasty was performed and once more the presence of black cartilage was noted. Alkaptonuria usually appears after age 30 and is usually asymptomatic until the involvement of the spine, hip, knee and shoulder joints. Therefore, orthopaedic surgeons must be suspicious of an atypical arthropathy in order to not be overwhelmed during surgery with the presence of darkened cartilage.
