Muscle mass correlates with rocuronium distribution volume and guides dose optimization in obese colorectal cancer patients

Table 5 Multiple linear regression analysis of skeletal muscle index and volume of distribution at steady state/skeletal muscle mass

Variable	β	Standardized β	t value	P value	95%CI
SMI (kg/m2)	0.142	0.612	7.486	< 0.001	0.104 to 0.180
Gender (Male = 1)	0.068	0.168	2.384	0.019	0.012 to 0.124
Serum albumin (g/L)	0.018	0.196	2.791	0.006	0.006 to 0.030
