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

backgroundBK virus is a polyoma virus which has been associated with impaired graft function in kidney transplant recipients. After primary infection, the virus becomes latent in the renal/urinary epithelium. In immunocompetent hosts, there are usually no pathological sequelae. CASE: An 11-year-old female on chronic immunosuppression for a severe auto-immune/inflammatory condition was referred to Paediatric Nephrology due to a persistently elevated serum creatinine. Extensive investigation yielded BK viruria and viraemia. Kidney biopsy showed multifocal lymphocytic tubulitis, with cytonuclear changes. Immunohistochemical staining for SV40 was positive, and a diagnosis of native kidney BK virus nephropathy was made.

conclusionWe present the first non-malignancy/transplant-associated paediatric case of BK virus nephropathy in a native kidney. In an era of increasing use of immunosuppressive medicines for a variety of indications, clinicians should include BK virus infection in their differential diagnosis for nephropathy in patients on chronic, high-dose immunosuppression.
