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

Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive disorder which causes high urinary 2,8-dihydroxyadenine (2,8-DHA) excretion, resulting in urolithiasis and crystal nephropathy. It is caused by mutations in the APRT gene. Even though it is an inherited kidney stone disease, the varied clinical presentations, even within a family with the same underlying genetic variants, can lead to delayed diagnosis with some only being recognized in adulthood and even, following a kidney transplant. First presentations include symptoms of reddish-brown diaper stains, urinary tract infections, urolithiasis, acute kidney injury from obstructive uropathy and/or intratubular 2,8-DHA crystallization or kidney failure. Siblings of index cases should be screened for APRT deficiency. An early diagnosis and treatment with xanthine oxidoreductase inhibitors (XORi) can preserve kidney function and/or prevent progressive kidney injury and kidney failure. In this review, we will discuss the pathophysiology, clinical presentations, investigations, and management of APRT deficiency.
