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

Maple syrup urine disease (MSUD) is a defect in the catabolism of the branched-chain amino acids; leucine, isoleucine, and valine. Affected patients may also develop hyperammonaemia of unknown etiology. This report describes a four-year-old girl with MSUD, who presented with decompensated hyperleucinaemia with hyperammonaemia. The oral administration of the N-acetylglutamate analogue, N-carbamylglutamate (NCG), 200 mg/kg/day as a loading dose, and 100 mg/kg/day as a maintenance dose, in combination with standard therapy resulted in a significant decrease of plasma ammonia levels. This observation suggests that NCG may be an important adjunct to standard therapy in the management of decompensated MSUD patients with high leucine and ammonia levels. Supportive evidence from either randomized controlled trials or a large prospective cohort study is needed to confirm this interesting finding.
