Effects of Peanut Butter Supplementation on Older Adults' Physical Function: A 6-Month Randomised Controlled Trial.
Trial report in Journal of cachexia, sarcopenia and muscle, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundNut consumption has been associated with a reduced risk of functional decline, but evidence from randomised controlled trials to support functional benefit is lacking. Therefore, this study aimed to investigate whether daily supplementation of peanut butter over 6 months, relative to usual care, can improve physical function in community-dwelling older adults.
methodsOne hundred and twenty older adults (aged ≥ 65 years) at risk of falls were randomly assigned to receive peanut butter (43 g/day, n = 60) or maintain usual care (control, n = 60) for 6 months. Outcomes assessed at baseline and 6 months included physical function (4-m gait speed [primary outcome], standing balance test, four-square step test [FSST], five times sit-to-stand [5STS] test time and muscle power, 30-s sit-to-stand (30-s STS) and timed up and go [TUG] tests), muscle strength (handgrip [HGS] and isometric knee extensor strength tests [KES]) and anthropometry/body composition (weight, body mass index [BMI], total lean and fat mass and appendicular lean mass). Linear regression models, adjusting for age, sex, baseline value of the dependent variable, BMI, physical activity and diet quality, estimated intention-to-treat intervention effects.
resultsA total of 108 (90%) participants completed the study. At baseline, 70% were female, and the mean ± SD age and BMI were 76.1 ± 4.6 years and 27.5 ± 4.2 kg/m
conclusionIn community-dwelling older adults at risk for falls, daily peanut butter consumption for 6 months improved 5STS time and muscle power based on 5STS, but not gait speed, muscle strength or body composition.
