S2 Supplementary Table 8：Full multivariate logistic regression results for all lipid parameters, muscle indices, and socioeconomic variables.

S2 Supplementary Table 8：Full multivariate logistic regression results for all lipid parameters, muscle indices, and socioeconomic variables.Complete results for VAI, AIP, NHDL, residual cholesterol, eGFR, frailty index, frailty status, ASM, Castelli index I/II, and SES. Three models are shown: crude, age/gender-adjusted, and fully adjusted (age, gender, living area, marital status, education, smoking, alcohol). OR and 95% CI are reported. Corresponds to Table 2.S2 Supplementary Table 9：Full threshold analysis results for all continuous exposures.Complete threshold analysis for VAI, AIP, NHDL, residual cholesterol, eGFR, frailty index, ASM, and Castelli index I/II. For each exposure, the table shows linear effect, inflection point (K), segment-specific effects (below/above K), sample sizes per segment, and log-likelihood ratio test P-value. All analyses are fully adjusted. Corresponds to Table 3.S2 Supplementary Table 10：Full interaction analysis results for all exposures stratified by education level.Complete interaction results for all exposures (VAI, AIP, NHDL, residual cholesterol, eGFR, frailty index, ASM, Castelli index I/II) across three education strata. OR and 95% CI are shown for crude, age/gender-adjusted, and fully adjusted models, along with P-value for interaction. Sample sizes: no formal education (n=1,279; SAL=298), high school and below (n=1,550; SAL=251), above high school (n=78; SAL=7). Corresponds to Table 4.
