Metabolic risk factors, blood pressure and atherogenic indices of cardiovascular disease across different quartiles of dietary sodium to potassium ratio among young semi-professional athletes with overweight or obesity.

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
backgroundPrevious studies have revealed the role of the dietary sodium-to-potassium ratio in predicting cardiovascular and total mortality. However, a limited number of studies have investigated the association between the dietary sodium-to-potassium ratio and individual biomarkers of metabolic disease in athletes. In this study, we aimed to compare metabolic, atherogenic, and anthropometric risk factors for cardiovascular disease across different quartiles of the dietary sodium-to-potassium ratio among young semi-professional athletes with overweight or obesity.
methodsIn this cross-sectional study, 637 young semi-professional athletes, aged 20-40 years, were selected from active athletic and fitness clubs. Anthropometric measurements were performed, and fasting blood sugar, serum lipids, and lipoprotein (a) [Lp(a)] were measured. Atherogenic indices, including the atherogenic index of plasma (AIP), Castelli risk index (CRI)-I, CRI-II, and lipid tetrad index (LTI), were calculated.
resultsParticipants in the highest quartile of the dietary sodium-to-potassium ratio were younger and had a higher waist-to-hip ratio (WHR) compared to those in the lowest quartile. Additionally, those in the highest quartile showed significantly higher serum total cholesterol and Lp(a) concentrations after adjusting for confounding factors (P < 0.05).
conclusionOur findings suggest that individuals in the higher quartiles of the dietary sodium-to-potassium ratio exhibit less favorable serum lipid profiles. Further longitudinal and interventional studies are needed to clarify the potential therapeutic role of reducing the dietary sodium-to-potassium ratio in managing cardiovascular disease risk factors.
