A randomized parallel-designed study evaluating the effect of an app-based nutritional concept for weight reduction and further cardiovascular risk factors: Insights from the PreVA study.
Trial report in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04717076 (PrevA Study - Evaluation of an App-based Nutritional Concept to Lower Cardiovascular Risk Factors), which is not on this 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.

Abstract
Introduction: Overweight is a major public health concern. Beyond traditional dietary therapy, mobile health (mHealth) applications have gained interest for their potential to support weight loss. However, evidence on their efficacy remains limited. This study evaluated the effectiveness of an app-based dietary concept for weight reduction and improvement of further cardiovascular risk factors. Methods: The PreVa study is a single-center, randomized, four-arm parallel intervention study comparing an app-based nutrition program with standard therapy involving personal counseling. Eighty adults with a body mass index between 25 and < 35 kg/m Results: After 12 weeks of energy reduction, weight loss was significantly greater in the intervention groups (-6.5 %, -7.3 %, -6.0 %) than in the control group (-2.1 %; Conclusion: The intervention groups achieved clinically meaningful weight loss and an improvement in blood lipid levels. The greatest effect is likely attributable to the individualized, nutrient-optimized menu plans rather than the type of counseling or delivery mode.
