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
Background: Nonnutritive sweeteners (NNS) are increasingly incorporated into ultraprocessed foods and beverages, yet psychosocial drivers of NNS consumption across age groups in low- and middle-income settings remain poorly characterized. Understanding how knowledge, attitudinal beliefs, and information sources shape NNS consumption is essential for designing effective nutrition interventions. Objectives: This study examined age-related patterns of NNS consumption among adolescents and adults and evaluated how knowledge, attitudes, and sources of nutrition information interact to influence consumption practices. Methods: A cross-sectional study was conducted among 2769 adolescents (10-19 y) and adults (≥20 y) in southeast Nigeria. Data were collected using a structured questionnaire assessing sociodemographic characteristics, NNS-related knowledge, attitudinal beliefs, consumption practices, and information sources. Mediation and conditional process analyses evaluated whether attitudinal beliefs mediated the knowledge-practice relationship and whether this mediation varied by knowledge level, age group, and information source. Logistic regression identified predictors of high NNS consumption. Results: Adolescents (83.1%) showed a significantly higher prevalence of NNS consumption than adults (16.9%) ( Conclusions: NNS consumption patterns exhibited significant age-related variance and are shaped by a complex interplay between knowledge, belief-based attitudes, and the prevailing information environment. Public health nutrition interventions must evolve beyond traditional knowledge dissemination and adopt a multifaceted approach that addresses information quality, food environments, and age-targeted programs.
