Study quality was evaluated using the Newcastle\u2013Ottawa Scale (NOS). Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated, and heterogeneity, subgroup, and sensitivity analyses were conducted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Eleven studies, including 3,595 patients from four countries, were included. Thyroid dysfunction was significantly associated with increased mortality in patients with liver failure (RR = 3.56, 95% CI: 2.77\u20134.57;\n                      <jats:italic>I\u00b2<\/jats:italic>\n                      = 36%). Subgroup analyses by sex, FT3 cut-off, and etiology (hepatitis B virus [HBV] vs. non-hepatitis B virus acute-on-chronic liver failure [non-HBV ACLF]) showed consistent associations. Additionally, a subgroup analysis comparing FT3 concentrations between survival and death groups in liver failure patients revealed a significant difference in FT3 levels between the two groups (mean difference [MD] = 0.89 [0.41, 1.37] for short-term mortality and MD = 0.42 [0.23, 0.61] for long-term mortality). Sensitivity analyses confirmed the robustness of the results. No substantial publication bias was observed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Thyroid dysfunction, particularly low FT3 levels, is associated with higher mortality rates in patients with liver failure.
