The restricted cubic spline regression between anthropometric indices and PhenoAgeAccel. The dose–response relationship was evaluated using restricted cubic spline regression for the ABSI (a), BRI (b), BMI (c), and C-index (d) and PhenoAgeAccel with covariates adjusted as in model 3. The odds ratio is represented by the red line and the 95% confidence interval is shown in pink. ABSI A Body Shape Index, BRI Body Roundness Index, BMI Body mass index, C-index Conicity Index.
