Inclusion and exclusion criteria of the study
Included studies were required to satisfy each of the following
criteria: (1) the study examined the independent parameters (including
liver stiffness measured by transient elastography and/or platelet
count) of clinically significant portal hypertension (CSPH) and reported
the odds ratios (ORs) and corresponding 95% confidence intervals (CIs)
of these independent parameters; (2) measurement of the hepatic venous
pressure gradient (HVPG) was used as the reference method; and (3) the
study design was a prospective or retrospective cohort design.
The exclusion criteria were as follows: (1) reviews, editorials,
conference abstracts, and letters; (2) studies unrelated to the topic;
(3) data incomplete or no HVPG. Supplementary Figure 1. displays the
