Table 4. Stepwise multiple regression analysis using SMM/wt as a dependent variable¹.

Items	β	95% CI		P	Adjusted R2
		Minimum	Maximum
Constant	38.90	29.97	47.88	< .0001	0.32
CRP–Alb ratio	−3.84	−7.05	−0.64	0.019
HOMA-IR	−0.18	−0.30	−0.06	0.004

Abbreviations: SMM/wt, skeletal muscle mass normalized for body weight; CRP–Alb ratio, ratio of C-reactive protein and albumin; HOMA-IR, homeostatic model assessment-insulin resistance.

¹Values are shown as regression coefficients (β) with a 95% confidence interval and adjusted R square (R²). The SLE and SLS of any potential factor or interaction in the stepwise variable selection were set at 0.1. Variables such as sex, age, and total energy intake were forced as a regressor during stepwise selection. Variables retained in the model are presented in the table.
