Adequacy of cervical cytology sampling with the Cervex brush and the Aylesbury spatula: a population based randomised controlled trial

An authors' error and a proof reading error occurred in this paper by Paola Dey and colleagues (21 September, pp 721–3). In table 2 under “Subgroup analysis” the numbers allocated the Cervex brush and the Aylesbury spatula in centres with historically low and high inadequate smear rates were transposed. These should have read: “Low (<6%) (n = 1278, n = 992)” and “High (>12%) (n = 2041, n = 1712).” In addition, the reference to “table 3” in the text was erroneous and left over from a previous version of the manuscript. There was not intended to be a table 3 in the published version.
