  • * Cumulative spontaneous loss was calculated from any or severe GORS in HUNT 2, respectively, to no GORS in HUNT 3/Mini-Q, excluding those using antireflux medication at least weekly.

  • Any gastro-oesophageal reflux symptoms (GORS): minor or severe complaints with heartburn or acid regurgitation; severe GORS: severe complaints with heartburn or acid regurgitation.

  • OR and 95% CI of losing GORS for each sex and age group.

  • § Age at follow-up in HUNT 3/Mini-Q.
