CORRECTION

In the BSG abstract supplement published in April, abstract 402 by Davies et al (Gut 2002;50(Suppl II):A109) contained an error. The sensitivity and specificity for recurrence were given as 85.7% and 71.4% respectively. The correct result should be a reversal of these values, with sensitivity being 71.4% and specificity being 85.7%. The authors apologise for the error.
