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

backgroundExogenous insulin may trigger immune-mediated complications, particularly among East Asian populations. Double diabetes, characterized by overlapping features of type 1 diabetes (T1D) and type 2 diabetes (T2D), may arise from insulin-induced autoimmunity. This study aimed to explore the association between high-risk human leukocyte antigen (HLA) class II genotypes and susceptibility to double diabetes in patients initially diagnosed with T2D.

aimTo investigate clinical and immunogenic features of patients who develop double diabetes following exogenous insulin therapy.

methodsWe retrospectively analyzed five cases from Peking Union Medical College Hospital and 18 cases identified from published literature. Patients were categorized into two groups: The T2D→T1D group, characterized by autoimmune progression, and the stable T2D (T2D→T2D). Clinical characteristics and HLA class II genotypes were compared descriptively between the two groups.

resultsA total of 23 patients were included in the analysis. Of these, 10 progressed from theT2D→T1D with autoimmune features, while 13 remained in the stable T2D→T2D group. There was no statistically significant difference in age at diagnosis between the two groups (57.10 ± 16.11 years

conclusionThese findings suggest that patients in the T2D→T1D group exhibit a stronger autoimmune genetic predisposition, characterized by an enrichment of high-risk HLA class II alleles. In contrast, individuals with stable T2D demonstrate greater HLA diversity and lack definitive autoimmune-associated markers.
