Black raspberry supplementation on overweight and Helicobacter pylori infected mild dementia patients a pilot study.
Article in NPJ science of food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05680532 (The Improvement of Black Raspberry in Obese and Mild AZ Patients Infected With H. Pylori), which is not on this map.

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.

Abstract
Alzheimer's disease (AD) is the most common form of dementia. H. pylori infection and overweight have been implicated in AD via the gut-brain axis (GBA). This study aimed to determine whether supplementation of BRBs has a meaningful effect on H. pylori infection, overweight, and AD development in a clinical trial setting. We conducted a randomized placebo-controlled clinical trial in patients with mild clinical dementia who also had H. pylori infection and were overweight. The study was conducted over 10 weeks, consisting of an 8-week intervention period (25 g powder of black raspberries, BRBs, or placebo twice daily, morning and evening) and a 2-week follow-up. The primary outcomes were changes in Clinical Dementia Rating (CDR), Urea Breath Test (UBT), and Body Mass Index (BMI). Consumption of BRBs improved cognitive functions (p < 0.00001), compared to the placebo group (p > 0.05). Besides, BRBs ingestion decreased H. pylori infection and BMI (p < 0.00001 and p < 0.05 respectively) while the placebo group stayed statistically the same (p = 0.98 and p = 0.25 respectively). BRBs significantly decreased inflammatory markers, improved oxidative index, and adiponectin (p < 0.05) compared to the placebo group, while adenosine monophosphate-activated protein kinase (AMPK) and leptin did not significantly change. BRBs modulated the abundance of several fecal probiotics, particularly, Akkermansia muciniphila. Our results provided that BRBs suppressed H. pylori infection, decreased BMI, and rebalanced the gut microbiome, which could improve cognitive functions in mild dementia patients. Longer and larger randomized clinical trials of BRB interventions targeting H. pylori infection, overweight, or mild dementia are warranted to confirm the results from this pilot trial.
