Low-Dose Fisetin Supplementation and Its Association With Chronic Inflammation in Middle-Aged and Older Adults: Study Protocol for a Triple-Blind, Randomised, Placebo-Controlled Trial.
Article in Basic & clinical pharmacology & toxicology, 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
Systemic chronic inflammation contributes to the development of many age-related chronic diseases and represents a promising target for interventions aiming at promoting healthy aging. Fisetin is a naturally occurring flavonoid with anti-inflammatory, antioxidant and senolytic effects in vitro and in animal models, but evidence from randomised controlled trials in humans is limited. This study is a triple-blind, randomised, placebo-controlled trial designed to investigate the association between daily fisetin supplementation and changes in plasma soluble urokinase plasminogen activator receptor (suPAR) levels, as well as the occurrence and severity of adverse events, in generally healthy middle-aged and older adults, with exploratory evaluation of additional biomarkers and functional outcomes. Participants aged ≥ 50 will be randomised to receive 100 mg of oral fisetin or placebo once daily for 7 weeks. The primary outcome is the between-group difference in the change in plasma levels of suPAR from Baseline to Week 7. The secondary outcome is the between-group difference in the occurrence and severity of adverse events during the study period. In addition, exploratory outcomes will evaluate the association of fisetin supplementation with other soluble and cellular biomarkers of inflammation, aging and cellular senescence, as well as measures of frailty, physical and cognitive function and subjective health.
