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

backgroundRefractory arthritis is a common problem in routine rheumatology practice, and can be a diagnostic challenge. In these cases, chronic Tropheryma whipplei (T. whipplei) infection is an important differential diagnosis that should be considered.

objectiveBased on five clinical cases, this case-based review describes the diagnostic and therapeutic principles in the management of chronic T. whipplei infection.

resultsWhipple's disease is a multisystemic infectious disease caused by the bacterium T. whipplei. The disease typically manifests with arthralgia, weight loss and diarrhoea. Joint involvement often develops years before gastrointestinal symptoms occur. In addition to systemic manifestations ("classic Whipple's disease"), T. whipplei can also lead to localized joint infections without gastrointestinal involvement. Articular manifestations of systemic and localized T. whipplei infections are commonly misdiagnosed as a sign of various forms of autoimmmune arthritis. DISCUSSION: Whipple's disease and localized T. whipplei joint infection should be considered in the diagnostic work-up of refractory arthritis. Synovial fluid analysis by means of specific polymerase chain reaction-based testing for T. whipplei is diagnostically ground-breaking.
