Effects of water-soluble mangosteen extract on cognitive function and neuropsychiatric symptoms in patients with mild to moderate Alzheimer's disease (WECAN-AD): A randomized controlled trial.
Article in Alzheimer's & dementia (New York, N. Y.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 2 of them syntheses that pooled 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.
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
Introduction: The water-soluble mangosteen pericarp extract's (WME) effect was investigated in Alzheimer's disease (AD). Methods: The participants received 4 mg/kg/day of WME for 24 weeks (low dose, n = 33), 4 mg/kg/day for 12 weeks and then 8 mg/kg/day for 12 weeks (high dose, n = 33); or a placebo (n = 42). The outcomes were neuropsychiatric test scores, safety, tolerability, and the blood 4-hydroxynonenal level. Results: The proportion of participants who achieved the minimum clinically important difference for the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog; -2.6 points) at 24 weeks was significantly higher in the low-dose group (and a trend in the high-dose group) than in the placebo group. WME appeared safe and well tolerated. At 24 weeks, the 4-hydroxynonenal level declined in both intervention groups. The participants with a 5% reduction in this level showed greater ADAS-Cog improvements. Conclusion: WME is a safe and well-tolerated cognitive enhancer in AD with varying benefits across individuals based on antioxidative response.
