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

backgroundCrohn's disease of the small intestine typically causes abdominal symptoms and nutritional problems, but renal consequences are rare. CASE PRESENTATION: We report a 70 year-old British Caucasian man with longstanding Crohn's disease of the small intestine complicated by multiple fibrotic strictures, who developed a rapid deterioration in his renal function around the same time as initiation of biologic therapy. Following investigation into the cause of his renal deterioration and eventually a renal biopsy, he was diagnosed with oxalate nephropathy leading to end-stage renal failure with creatinine peaking at 604 umol/l. The pathophysiology of enteric hyperoxaluria in Crohn's disease is discussed.

conclusionAwareness of hyperoxaluria and potential oxalate nephrotoxicity in patients with small intestinal Crohn's and an intact colon should help clinicians advise such patients on dietary and fluid intake modification at an early stage.
