Physical activity modifies the association between dietary fiber and hypertension: A cross-sectional study of U.S. adults from NHANES 2007-2018.

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
ObjectiveDietary fiber and physical activity are independent determinants of blood pressure. However, their interaction regarding hypertension remains poorly understood. This study examined the association between dietary fiber intake and hypertension. It also aimed to determine if this relationship is modified by physical activity in a representative sample of U.S. adults.MethodsThis cross-sectional study used data from 26,556 U.S. adults (National Health and Nutrition Examination Survey 2007-2018). Dietary fiber intake was assessed via two 24-h recalls and categorized into quartiles. Hypertension was defined by measured blood pressure, self-reported diagnosis, or antihypertensive medication use. Physical activity was quantified and divided into three levels. Missing covariate data were addressed using multiple imputations. Survey-weighted multivariable logistic regression was used to examine the association. A multiplicative interaction term was introduced to assess effect modification by physical activity. An XGBoost was also developed and interpreted using SHapley Additive exPlanation to explore nonlinear associations.ResultsIn the fully adjusted model, lower dietary fiber intake was associated with increased odds of hypertension (OR for Q3 vs. Q4: 1.25; 95% CI [1.08, 1.44]). This relationship showed a potential interaction with physical activity (
