Synthesis in Current diabetes reports, 2025. The graph read 2 numbers from its abstract, feeding 2 cells of the map, but none could be read as for or against, so it casts no vote. It also reports an association that does not count as treatment evidence, such as HR 0.77 (0.70 to 0.84) for major adverse cardiovascular events (MACE). Not yet cited in PubMed.

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.

4 · 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

The marked sentences are the ones the graph read a number from.

purpose of reviewAtherosclerotic cardiovascular disease (ASCVD) is the leading cause of death in patients living with type 1 diabetes (T1D). Dyslipidemia is a frequent risk factor in this population. Although statin therapy has demonstrated cardiovascular (CV) benefits in diabetes overall, specific evidence in T1D remains limited. This systematic review aims to evaluate the impact of statins on clinical and surrogate atherosclerosis-related outcomes in patients with T1D without established ASCVD. RECENT

findingsStatin use was associated with a significant reduction in the risk of major adverse cardiovascular events (MACE), with a pooled hazard ratio (HR) of 0.77 (95% CI: 0.70-0.84; low certainty), and a mean low-density lipoprotein cholesterol (LDL-C) reduction of 30.3 mg/dL (95% CI: -47.02 to -13.58; moderate certainty). Reductions in ApoB and non-HDL cholesterol were also reported. We conducted a systematic review following PRISMA guidelines. Searches were performed in PubMed, EMBASE, and Epistemonikos from inception to June 2025 using terms related to T1D, statins, and primary prevention. Eleven studies were included-nine randomized controlled trials (RCTs) and two cohort studies. Six (four RCTs and two cohorts) were eligible for meta-analysis of two primary outcomes; the remaining were summarized narratively. Statin use in T1D patients without ASCVD was associated with improved lipid profiles and reduced MACE. These findings support considering statins as a preventive strategy in this population, although prospective studies with hard outcomes are needed to better identify patients most likely to benefit.
