Glucose-Lowering Therapies and Cognitive Decline: From Molecular Mechanisms to Clinical Evidence and Future Perspectives.
Review in Advances in therapy, 2026. 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
Several lines of evidence suggest the relationship between diabetes and cognitive decline. Patients with a diagnosis of type 2 diabetes (T2D) present an increased risk of Alzheimer's disease (AD) development than the general population, and it is known that brain insulin resistance (IR) plays a key role in the conversion from mild cognitive impairment (MCI) into AD. During recent years, emerging therapeutic perspectives have been proposed with the aim of targeting T2D-related cognitive impairment, and glucose-lowering drug classes, especially glucagon-like peptide 1 receptor agonists (GLP-1RAs) and sodium glucose cotransporter inhibitors (SGLT2is), demonstrated neuroprotective effects and a positive effects on cognitive function acting by several molecular mechanisms including anti-inflammatory activity, modulation of insulin signaling, and promoting the neurogenesis process. Different clinical trials showed their ability in preventing neurodegenerative decline, with numerous phase II and III trials underway in populations with AD; however, although preclinical evidence is promising and some clinical data are encouraging, translating these results into established therapeutic strategies requires larger, randomized, and controlled clinical trials with extended follow-up period, standardized cognitive assessments, and inclusion of molecular and imaging biomarkers. Addressing these gaps will be essential to determine whether glucose-lowering drug classes can be introduced into clinical practice to prevent or slow cognitive decline in patients with T2D, exerting neuroprotective activity beyond their effect on glycemic control.
