Abstract

Background: Gamma-glutamyltransferase (GGT) levels in the blood can be a sensitive marker of liver injury but the extent to which they give insight into risk across multiple outcomes in a clinically useful way remains uncertain. Methods: Using data from 293,667 UK Biobank participants, the relationship of GGT concentrations to self-reported alcohol intake and adiposity markers were investigated. We next investigated whether GGT predicted liver-related, cardiovascular (CV) or all-cause mortality, and potentially improved CV risk prediction. Findings: Higher alcohol intake and greater waist circumference (WC) were associated with higher GGT; the association was stronger for alcohol with evidence of a synergistic effect of WC. Higher GGT concentrations were associated with multiple outcomes. Compared to a GGT of 14.5 U/L (lowest decile), values of 48 U/L for women and 60 U/L for men (common upper limits of 'normal') had hazard ratios (HRs) for liver-related mortality of 1.83 (95% CI 1.60-2.11) and 3.25 (95% CI 2.38-4.42) respectively, for CV mortality of 1.21 (95% CI 1.14-1.28) and 1.43 (95% CI 1.27-1.60) and for all-cause mortality of 1.15 (95% CI 1.12-1.18) and 1.31 (95% CI 1.24-1.38). Adding GGT to a risk algorithm for CV mortality reclassified an additional 1.24% (95% CI 0.14-2.34) of participants across a binary 5% 10-year risk threshold. Interpretation: Our study suggests that a modest elevation in GGT levels should trigger a discussion with the individual to review diet and lifestyle including alcohol intake and consideration of formal liver disease and CV risk assessment if not previously done.

  • GGT reflects liver adiposity in addition to alcohol intake signals.

    “liver adiposity in addi tion to alcohol intake signals (GGT)”
  • Leptin reflects total obesity or percent fat mass.

    “consistent with their roles as biomarkers reflecting total obesity or percent fat mass (leptin)”

    From Comprehensive Long-Term Changes in Cardiovascular Risk Biomarkers With Tirzepatide (2026) · cites this paper as [30]

    The Methods section describes BMI, waist circumference and liver-marker measurements, but does not identify leptin as a biomarker of obesity or percent fat mass. Searches of our copy for “leptin” and “percent fat mass” found no passage addressing that relationship. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • HOMA-IR reflects insulin resistance and ectopic and total fat.

    “insulin resistance and ectopic and total fat (HOMA-IR). 2,29-31”

    From Comprehensive Long-Term Changes in Cardiovascular Risk Biomarkers With Tirzepatide (2026) · cites this paper as [30]

    The Methods (Study design and participants; Statistical analysis, pages unavailable) describe BMI, waist measurements, diabetes status, and liver markers, but do not discuss HOMA-IR. Searches for HOMA-IR, insulin resistance, and ectopic or total fat found no passage stating that HOMA-IR reflects those measures. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
