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

backgroundCobalamin C (cbl-C) defect is an inherited autosomal recessive disorder that commonly affects the central nervous system of infants. Severe pulmonary hypertension (PH) and diffuse lung lesions are unusual clinical manifestations, especially among adults. CASE SUMMARY: A 25-year-old man with hypoxaemia, diffuse lung lesions, and PH, suddenly developed nausea, vomiting, headache, and worsening of dyspnoea. Metabolic screening showed elevated serum levels of methylmalonic acid and homocysteine, and genetic testing revealed DISCUSSION: cbl-C is a rare cause of PH and can present with severe PH and diffuse lung lesions in adults. Given that the condition is treatable, a careful metabolic screening should be considered when a diagnosis of PH is made.
