Ochronosis of the knee with secondary osteoarthritis requiring total knee replacement in a patient with cryptogenic organising pneumonia.
Article in BMJ case reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Ochronosis is a rare autosomal recessive metabolic disease caused by homogentisic acid oxidase enzyme deficiency. High homogentisic acid levels will eventually result in black deposits in skin, sclerae, connective tissues and urine (alkaptonuria). It can lead to early degeneration of connective tissues and cartilage. Ochronosis can damage normal cartilage, leading to secondary osteoarthritis. The diagnosis is often delayed because of its low prevalence and non-specific early symptoms. In our patient, the secondary osteoarthritis due to ochronosis deposits in the cartilage was treated by total knee arthroplasty, with good clinical outcome. This article reports the first case of ochronosis with secondary osteoarthritis of the knee in a patient previously diagnosed with cryptogenic organising pneumonia (COP).
