Note: Spearman’s correlation coefficients were used to analyze the intensity of the correlations between fluid intake, hydration status, and AFI. Pearson’s correlation coefficients were used to analyze the intensity of the correlations between fluid intake and urine biomarkers. A p-value of less than 0.05 was considered significant. SSBs: sugar-sweetened beverages; TFI: total fluid intake.
