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

We report a 52-year-old man with autoantibody-negative type 1 diabetes (T1D) who presented with severe insulin resistance (IR). Whole-exome sequencing (WES) identified a heterozygous mutation in the IGF2BP2 gene (c.248A>G, p. Lys83Thr; rs4402960), associated with type 2 diabetes (T2D) risk. Despite intensive insulin therapy, the patient exhibited markedly elevated insulin requirements (>1.5 U/kg/day; total, 140 U/day) alongside persistent hyperglycemia. The estimated glucose disposal rate (eGDR) was 4.32 mg/kg/min, indicating significant IR. The Somogyi phenomenon was ruled out via continuous glucose monitoring (CGM), and the patient was deemed to have IR. The addition of metformin, acarbose, and dapagliflozin reduced insulin requirements and significantly improved glycemic control. This case suggests that T2D-associated genetic variants may contribute to IR in T1D and underscores the potential value of genetic testing in guiding targeted oral combination therapy.
