Nutrient Displacement Associated with Replacing Intake of Usual Snacks with Pecans: An Exploratory Analysis of a Randomized Controlled Trial.
Article in Current developments in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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
Background: The effect of instructions to replace usual snacks with nuts on nutrient displacement is unknown. Objectives: This analysis aimed to investigate nutrient displacement and changes in food pattern component intake that occur with instructions to consume 57 g/d of pecans in place of usual snacks in adults at increased risk of cardiometabolic diseases after 6 wk and 12 wk. Methods: Data from a 12-wk randomized controlled trial were used for this exploratory analysis. Adults at risk of cardiometabolic diseases were provided with 57 g/d of pecans and instructed to replace habitually consumed snacks with the provided pecans. The control group was instructed to continue consuming their usual diet. Participants completed 3 24-h recalls at baseline, week 6, and week 12 for assessment of nutrient and food pattern component intake. Nutrient displacement was calculated according to a previously described method to estimate the extent to which nutrients provided by pecans displaced nutrients from other foods. Results: At 12-wk, partial nutrient displacement occurred for energy (84%; 331 ± 47.8 kcal), total fat (55%; 22.6 ± 0.50 g), monounsaturated fat (47%; 10.9 ± 0.23 g), polyunsaturated fat (46%; 5.71 ± 0.07 g), and fiber (60%; 3.29 ± 0.03 g) in the pecan group. Nutrient displacement >100% was observed for carbohydrates (343%; 27.1 ± 0.12 g), and full displacement of saturated fat occurred at week 12 in the pecan group. In the pecan group, intake of nuts and seeds [mean difference 2.3 oz-eq; 95% confidence interval (CI): 1.0, 3.6], oils (19.2 g; 95% CI: 12.6, 25.7), and total protein foods (2.3 oz-eq; 95% CI: 1.0, 3.6) increased. No other differences in food pattern components were observed. Results at week 6 were relatively consistent with those observed at 12-wk. Conclusions: Instructions to replace usual snacks with pecans resulted in the partial displacement of energy, total fat, unsaturated fats, and fiber. Additionally, pecan consumption increased intakes of food pattern components emphasized in healthy dietary patterns.This trial is registered at clinicaltrials.gov as NCT05071807.
