Circulating long non-coding RNAs as predictors of type 2 diabetes mellitus development: results from the CORDIOPREV study.
Article in Cardiovascular diabetology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundType 2 diabetes mellitus (T2DM) is a growing global health challenge. Conventional diagnostic tools have limited sensitivity and specificity for early-stage disease. In this context, long non-coding RNAs (lncRNAs) have emerged as promising biomarkers for T2DM risk. However, studies exploring their predictive value remain limited. This study aimed to evaluate the potential of circulating lncRNAs in T2DM development and to assess their interaction with dietary interventions.
methodsThe study included 462 non-diabetic participants from the CORDIOPREV study, followed for 5 years under Mediterranean or low-fat diet interventions. Expression levels of 22 circulating lncRNAs were quantified by qPCR. A series of statistical and machine learning methods were applied.
resultsRandom forest analysis identified four lncRNAs (XIST, LINC01116, CASC2, LINC01370) as predictive of T2DM incidence. The combination of these lncRNAs with clinical variables significantly improved prediction performance (AUC = 0.730) compared to models with Hb1Ac (p = 0.015) or clinical variables alone (p < 0.001). Regarding the constructed lncRNA score from the previous model, a lower lncRNA score was associated with a reduced risk of developing T2DM (HR 0.37 (0.24-0.59), p < 0.001), and showed an inverse correlation with the disposition index among individuals following a Mediterranean diet (r = - 0.18, p = 0.009).
conclusionCirculating lncRNAs, particularly integrated into an epigenetic score, represent promising predictive biomarkers for T2DM development. The interaction with dietary intervention-especially the Mediterranean diet-supports their potential use in guiding personalized dietary strategies for T2DM prevention in high-risk populations.
