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

backgroundIndividuals of South and East Asian ancestry have a higher risk of type 2 diabetes, often driven by insulin deficiency due to impaired beta-cell function. The transcription factor XBP1 supports beta-cell survival by reducing cellular stress, but its role in diabetes risk and glucose regulation remains unclear. This study aimed to evaluate the impact of XBP1 expression on diabetes risk, beta-cell function, glycaemic traits, and treatment response across ancestries.

methodsWe performed colocalisation analyses to test whether XBP1 expression in pancreatic islets and type 2 diabetes share causal variants. A lead variant regulating XBP1 expression was identified and analysed in two South Asian cohorts from India to assess associations with beta-cell function and glucose levels. We further assessed glycaemic control using HbA1c in cohorts of British South Asians and white Europeans. We examined the effect of the variant on drugs designed to improve insulin secretion.

resultsXBP1 expression colocalises with diabetes risk in East Asians but not in white Europeans, and lower expression is associated with higher risk of diabetes. The lead SNP of the eQTL (rs7287124) is more common in East (65%) and South Asians (50%) compared to white Europeans (25%). rs7287124 is associated with lower beta-cell function using HOMA-B (P = 5 × 10

conclusionsXBP1 expression is associated with diabetes risk with particular value in under-represented populations at risk of young, non-obese onset diabetes.
