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: Type A insulin resistance syndrome (TAIRS) is a rare inherited disorder caused by mutations in the insulin receptor (INSR) gene. It is characterized by severe insulin resistance, hyperandrogenism, and acanthosis nigricans. Its clinical manifestations overlap with those of polycystic ovary syndrome (PCOS), making it prone to misdiagnosis, particularly in adolescent females. Currently, the diagnosis of TAIRS relies on clinical evaluation and genetic confirmation, while long-term management strategies remain limited and challenging. Case presentation: We report a 12-year-old female proband who presented with severe hyperinsulinemia, hyperandrogenism (hirsutism), acanthosis nigricans, and polycystic ovarian changes despite a non-obese phenotype. Whole-exome sequencing identified a Conclusions: This case is attributed to a
