High transaminase (HT) incidence and remission in the surgery and the control groups at 2- and 10-year follow up.

<p>HT group was defined if one or both transaminase levels were above the following cut-offs: AST ≥33 U/L (men) and 29 U/L (women) ALT levels ≥43 U/L (men) and 30 U/L (women). Incidence and remission are expressed as proportion of individuals; the bars indicate the 95% confidence intervals. *P value <0.001, surgery vs. control group. A. Control n = 916 and 621 at 2- and 10-year FU; Surgery n = 857 and 618 at 2- and 10 -year FU. B. Control n = 519 and 332 at 2- and 10-year FU; Surgery n = 731 and 491 at 2- and 10-year FU. <i>Abbreviations:</i> FU, follow up; HT, high transaminase; AST, aspartate transferase; ALT, alanine transferase.
