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

Background: Rabson-Mendenhall Syndrome (RMS), a rare hereditary form of insulin resistance, is marked by severe hyperinsulinemia and early-onset acanthosis nigricans (AN) during childhood. Case presentation: A case of a 15-month-old girl was reported, presenting with widespread acanthosis nigricans, growth retardation, dysmorphic facial features, and hypertrichosis. Laboratory results indicated fasting hypoglycemia and hyperinsulinemia, while her oral glucose tolerance test (OGTT) remained normal. Whole-exome sequencing revealed two novel mutations in the insulin receptor gene (INSR): a c.3392 C > G missense/frameshift mutation in exon 19 and a c.4007_4010delAGAG deletion in exon 22. Conclusion: Acanthosis nigricans (AN) can serve as a clinical marker that strongly suggests underlying metabolic syndromes, making genetic analysis essential for confirming the diagnosis.
