Statistical analysis
Categorical variables are summarized
as counts (percentages) and continuous variables are presented as the
median with interquartile range (IQR).
Univariate binary logistic
regression was used to explore the factors correlating with cumulative
LBAI. The cumulative incidence rates of mortality were assessed using
the Kaplan-Meier method and significant differences between the
subgroups were determined using the standard log-rank test. Univariable
and multivariable Cox proportional hazard regression was used for the
survival analysis associated with liver injury markers and other risk
factors for mortality. All
descriptive statistical analyses were conducted with SPSS version 23.0
(IBM Corp, USA) and analytical analyses were done using R version 4.0.0
(R Foundation for Statistical Computing, Austria). We judged a two-sided
p less than 0.05 statistically significant.
