AJHP and CJHP both cited a slightly lower percentage of journal articles (77%-80%) and a correspondingly higher percentage of miscellaneous, books, and government documents.
Zone 1 of Set B (CJHP) included 9 journal titles (1.4%) accounting for the top third (33.3%).
AJHP and CJHP had a larger gray literature component, with 16% in AJHP and 18% in CJHP.
Overall, the journal titles found in Zone 1 and Zone 2 of Set B (CJHP) largely reflected the same titles as those found in Set A (Table 5 and online only Tables 6 and 7).
CJHP is an example of this, when in 1995, they were dropped from the list of journals indexed in MEDLINE and were not reinstated until 2009 .
