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

Ornithine transcarbamylase deficiency (OTCD) is a disorder of the urea cycle. A 19-year-old man with no medical or family history presented with sudden alterations in mentation after weight training and increased protein intake. His plasma ammonia level increased to >235 μmol/L, and intensive blood purification therapy was promptly initiated based on the assumption of acute hyperammonemic encephalopathy due to late-onset OTCD. On day 5, his mental status and plasma ammonia levels normalized, allowing discontinuation of blood purification therapy. An amino acid analysis confirmed the presence of OTCD. Prompt and intensive blood purification therapy is necessary to treat hyperammonemic encephalopathy due to late-onset OTCD.
