Q1 is the 1st quartile and Q3 is the 3rd quartile. The percentile value was referenced against a normal population controlling for age and gender, which are unit less. The units for the raw values were specified in the row names. The smaller eccentricity indicates a rounder body shape. HU, Hounsfield Units.
Values are presented as median (range) or number (%). For continuous variables, median and interquartile were shown, and p-values were from Mann-Whitney U test. For categorical variables, counts (and frequency if binary) were shown, and p-values were from Fisher exact test. BMI, body mass index; HCV, hepatitis C virus; ECOG, Eastern Cooperative Oncology Group; AFP, α-fetoprotein; MELD, Mayo End Stage Liver Disease score.
