Tea and cognitive health in aging: Current evidence and future directions.
Review in Medicine, 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
The health benefits of tea drinking have been extensively studied, and in the past 20 years, there has been increasing interest in the role of tea drinking in promoting cognitive health among older adults. This review aims to analyze existing evidence on the benefits of tea drinking to promote cognitive health from both observational and interventional studies. Using a narrative approach and in-depth discussion, the major studies on tea and cognitive health were identified and summarized. Gaps in knowledge and future directions are discussed. Solid evidence from prospective cohort studies demonstrates that tea drinking slows cognitive decline, lowers the risk of cognitive impairment, and improves cognitive function. Current evidence from randomized controlled trials is inadequate for a definitive conclusion. Tea is associated with better cognition in aging. Further clinical trials should be conducted to validate the claim that tea drinking can promote cognitive health in aging.
