Footnotes

• In celebration of the 20th anniversary of Injury Prevention, we asked our readers and editorial board to identify six of the most influential papers available in the journal's archive. We will republish one of these in each of the six issues of the 2015 volume. In addition, current editorial board members have been asked to comment on the importance of the paper from a personal or professional perspective. We hope these highlights from past volumes will encourage you to explore the Injury Prevention archive on your own.

• This is a reprint of a paper that first appeared in Injury Prevention 1998 volume 4, pages 302–7.
