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

Mutations in the PNPLA2 gene cause neutral lipid storage disease with myopathy (NLSDM) or triglyceride deposit cardiomyovasculopathy. We report a detailed case study of a 53-year-old man with NLSDM. The PNPLA2 gene was analyzed according to the reported method. We summarized the clinical, laboratory, and genetic information of 56 patients, including our patient and 55 other reported patients with homozygous or compound heterozygous mutations in the PNPLA2 gene. We found a novel homozygous mutation (c.194delC) in the PNPLA2 gene that resulted in frameshift. The patient suffered from normal-tension glaucoma and pulmonary cysts, symptoms that are relatively common in the elderly but were not previously reported for this disease. Our summary confirmed that Jordan's anomaly, polymorphonuclear leukocytes with lipid accumulation, was the most consistent finding of this disease. Because this disease is potentially treatable, our results may help rapid and correct diagnosis.
