NOTE: Values reported in bold are statistically significant.
Models were mutually adjusted for all HLI variables. Cases and controls were matched on age at blood collection (±1 year), sex, study center, date (±2 months), and time of day at blood collection (±3 hours), fasting status at blood collection (<3/3–6/>6 hours); women were additionally matched on menopausal status (pre/peri/postmenopausal) and hormone replacement therapy. The mediator models were linear. The outcome models were computed through conditional logistic regressions. In the mediation analysis, the exposure was the original modified HLI lifestyle factor, the mediator was the associated M-score (metabolic profile), and the outcome was HCC.
