Serum creatinine-to-cystatin C-to-waist circumference ratio

1. Serum creatinine-to-cystatin C-to-waist circumference ratio lowers the risk of severe airflow limitation in humans (HRs: 0.49 to 0.73, all p < 0.05).

   “Cox regression analysis revealed a decreased risk of SAL in the quartiles (Q2-4) compared to the first quartile of the CCR/WC ratio (hazard ratios [HRs]: 0.49 to 0.73, all p < 0.05).”

2. Serum creatinine-to-cystatin C-to-waist circumference ratio is associated with severe airflow limitation in humans (OR: 0.64, 95% CI: 0.47 to 0.85, p = 0.003).

   “and an inverse association relationship with SAL (OR [odds ratio]: 0.64, 95% confidence interval [CI]: 0.47 to 0.85, p = 0.003).”

1. Serum creatinine-to-cystatin C-to-waist circumference ratio is associated with peak expiratory flow in humans (β = 25.95, 95% CI: 12.72 to 39.18, p < 0.001).

   “This study revealed a positive association between the CCR/WC ratio and lung function (PEF: β [partial coefficient]: 25.95, 95%CI: 12.72 to 39.18, p < 0.001”
