Re the article "The contribution of airway structure to early childhood asthma", by McKay KO and Hogg JC, in the 16 September supplement to the Journal, Early childhood asthma: what we know and what we need to know (Med J Aust 2002; 177: S45-S47). The last two lines of the figure caption on page S46 were omitted. The full caption should read:

"The vessels in the submucosa (a) are smaller than the vessels in the adventitia (c), and the vessels that pass through the muscle layer (b) connect them. These two sets of vessels are perfused in series, providing a basis for a difference in the nature of the inflammatory reaction in the submucosa and lumen compared with the peribronchiolar space."

The html and pdf versions of the article were corrected on Monday 30 September 2002.
