Table 3. Multivariable associations of baseline variables with change in LCBI (n=47).

Parameter	β coefficient	95% CI	standardized β	P value
Baseline LCBI	−0.24	[−0.45, −0.03]	−0.31	0.02
Follow-up period	0.04	[−0.07, 0.15]	0.11	0.47
Clinical presentation of CAD	306.22	[109.95, 502.49]	2.31	0.003
ABCG1 CEC without clinical presentation of CAD	10.39	[−21.72, 42.51]	0.11	0.52
ABCG1 CEC with clinical presentation of CAD	−76.92	[−126.41, −27.44]	−0.79	0.003

A plus value of β coefficient, with concomitant P value less than 0.05, indicates that the variable is positively associated with change in coronary lipid burden; A minus value of β coefficient, with concomitant P value less than 0.05, indicates that the variable is negatively associated with change in coronary lipid burden. ABCG1 CEC, ATP-binding cassette transporter G1-mediated cholesterol efflux capacity; CAD, coronary artery disease; CI, confidence interval; LCBI, lipid core burden index.
