AB A bimodal birth distribution and seasonal trend has been previously reported in cystic fibrosis. The present study of 412 cases in Manchester and Bristol does not confirm the presence of a seasonal trend or any cyclic variation, and in general the trends in the present study are the reverse of those in the previous reports.
