Visit-to-Visit Variability in Lipid Levels and Risk of Incident Heart Failure in Adults With Type 2 Diabetes.
Article in Diabetes care, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveLimited data exist on the relation between long-term variability in blood lipid fractions and incident heart failure (HF) in the setting of type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND
methodsAmong 9,443 participants with T2DM from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study, with lipid measurements available at six time points (baseline, 4, 8, 12, 24, and 36 months), we assessed variability in total cholesterol (TC), LDL cholesterol, HDL cholesterol, and triglycerides (TG) across visits, using coefficient of variation (CV), SD, and variability independent of the mean. Cox proportional hazards models were employed to estimate adjusted hazard ratios (HRs) for incident HF.
resultsDuring a median follow-up of 5.0 years, 345 participants developed HF. Participants in the highest quartile of CV of TC had a 68% higher relative risk of HF compared with those in the lowest quartile (adjusted HR [aHR] 1.68, 95% CI 1.22-2.30). Similarly, those in the highest quartile of LDL cholesterol CV had a 76% higher relative risk (aHR 1.76, 95% CI 1.27-2.42) of HF, while those in the highest quartile of HDL cholesterol CV had a 53% higher risk (aHR 1.53, 95% CI 1.13-2.06). For TG CV, participants in the highest quartile had a 49% higher risk of HF compared with the lowest quartile (aHR 1.49, 95% CI 1.09-2.04). Similar patterns were observed for other variability metrics.
conclusionsIncreased variability in TC, LDL cholesterol, HDL cholesterol, or TG is independently associated with a higher HF risk among individuals with T2DM.
