1 · What the graph read from it

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.

2 · The registry

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

backgroundMetabolic dysfunction-associated fatty liver disease (MAFLD) is a growing public health concern among children and adolescents with overweight and obesity. Diet quality, particularly antioxidant intake, may play a role in hepatic metabolic regulation. This study investigated the association between dietary total antioxidant capacity (DTAC) and MAFLD, and examined the mediating role of flavonoid subclasses.

methodsIn this cross-sectional study, 505 overweight and obese Iranian children and adolescents aged 7-18 years were recruited. DTAC was estimated using a validated 147-item food frequency questionnaire and the ferric reducing antioxidant power (FRAP) method. MAFLD was diagnosed via ultrasonographic evidence of hepatic steatosis in combination with overweight/obesity. Logistic regression and restricted cubic spline models assessed associations, and mediation analysis evaluated indirect effects of flavonoids.

resultsThe mean DTAC was 8.7 ± 3.8 overall, 8.3 ± 3.3 in the MAFLD group, and 9.0 ± 4.1 in the non-MAFLD group. In fully adjusted model, participants in the highest DTAC tertile had 62% reduced odds of MAFLD compared to the lowest tertile (OR: 0.38; 95% CI: 0.18-0.82; P-trend = 0.03). Spline analysis confirmed a non-linear inverse association. Mediation analysis revealed that flavonols and anthocyanidins significantly mediated the DTAC-MAFLD relationship, accounting for 74.4% and 38.4% of the total effect, respectively.

conclusionHigher dietary antioxidant capacity is inversely associated with MAFLD in overweight and obese youth, partly through the intake of specific flavonoid subclasses. These findings emphasize the value of antioxidant-rich diets for pediatric liver health and highlight the need for longitudinal studies or clinical trials to confirm causal relationships.
