Hypothesis

The study investigates the relationship between oxidative balance indicators and the risk of chronic kidney disease (CKD).

Conclusion

Higher levels of oxidative balance indicators, particularly the Oxidative Balance Score (OBS) and Pro-Oxidant-Antioxidant Balance (PAB), are associated with a reduced risk of CKD.

Supporting Evidence

  • Higher OBS and PAB levels were significantly associated with a reduced risk of CKD.
  • OBS demonstrated the strongest predictive ability for CKD risk among the indicators.
  • TAC showed no significant association with CKD.
  • Participants in higher quartiles of OBS had a significantly lower risk of CKD.
  • ROC curve analysis indicated that OBS had a superior predictive ability for CKD risk.

Takeaway

This study found that eating healthy and balancing antioxidants can help lower the risk of kidney problems.

Methodology

A cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 2009–2018, employing logistic regression models.

Potential Biases

Potential reporting bias due to self-reported dietary and lifestyle data.

Limitations

The cross-sectional design limits causal inference, and reliance on self-reported data may introduce bias.

Participant Demographics

Participants included a diverse population from the NHANES surveys, with a mean age of 47.67 years and a gender distribution of 48.4% male.
