“…In several more recent reviews, lead is not mentioned at all (3,4,7,8), while the topic is treated very briefly with a maximum of three references in others (1,2,5,9,12). Only in the early review by Warshaw from 1960 (13), in Kurppa et ai's review of 1984 (6), and in the reports of Rosenman (10,11) is a reasonably thorough discussion of the possible lead-CVD relationship included. These authors give six to twelve empirical references.…”
