(RC = \(-\)0.83, 95% CI = [\(-\)1.56; \(-\)0.09]) at the second CCT. Moreover, these patients also showed an increment in EAT % in the Q4 (RC = 2.03; 95%CI = [\(-\)0.19; 4.24]), which was the fat quartile with a more positive density. One of the four patients reporting >45% fat in the Q4 at the second CCT was normal-weight, while the other three were overweight/obese. These observations were excluded, and multivariate multiple linear regression analysis was repeated on two reduced patient groups. A sensitivity analysis confirmed the results in the normal BMI group. A unitary increase in EAT % in the Q1 at the first CCT confirmed an increase in the Q1 (RC = 1.08, 95% CI = [0.17; 1.99], \(p\) = 0.023) and a decrease in the Q3 (RC = \(-\)1.21, 95% CI = [\(-\)2.10; \(-\)0.31], \(p\) = 0.011) at the second CCT.
