Editor,—Recently, the authors of two leading articles, Triadafilopoulos (Gut 2000;46:144–46) and Shepherd (Gut2000;46:147–49) referred to our paper inGut.1 We would like to draw attention to the fact that the legend in tables 4 and 5 in our paper should be read as (cm.month), (squares.month), and (%.month) since the variable is the area under the curve (AUC), which is the product of length or surface and time. The printed notation (with a slash) might suggest that the figures concern the change per month. In spite of our suggested change in the galley proof, this notation was maintained. Nevertheless, it does not change the purport of our conclusion, nor the discussion in both leading articles.
