Dietary supplement consumption among active individuals in Saudi Arabia.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundDespite the increasing use of dietary supplements in Saudi Arabia, accurate information on their consumption patterns and predictors is essential for effective policy planning.
objectiveThis study aimed to estimate the prevalence of dietary supplement consumption, assess perceptions regarding their health effects, and identify demographic, health-related, and knowledge- and practice-based factors influencing their use among active individuals in Saudi Arabia.
methodsThis cross-sectional study identified predictors of dietary supplement consumption using a Likert-scale questionnaire adapted from validated local and international tools with minor modifications. Structural equation modeling was conducted by defining multiple sets of regression equations. The analyses were performed using R software (Version 4.1.2) with the lavaan and semPlot packages. A two-tailed p-value < 0.05 was considered statistically significant.
resultsA total of 3,800 active individuals from 13 Saudi Arabian regions participated in this study. The prevalence of dietary supplement use among active individuals was 63.82%. Health characteristics and knowledge and practice domains showed a highly significant influence on supplement consumption, whereas the demographic domain did not show a significant association in the structural equation model, although several demographic variables were significantly associated with supplement use in bivariate analysis.
conclusionThe prevalence of dietary supplement use among physically active individuals in Saudi Arabia exceeded the prevalence rates reported in several international populations, with more than three out of every five participants indicating use of dietary supplements.
