Surgeons from the University of California, San Diego examined 110 emails sent to the senior author from 29 publishers during a six-week period and early 2017. Nearly all were requesting manuscript submissions. The 29 publishers represented 113 different surgery journals most of which had existed for two years or less. Only 12 were indexed in PubMed, and of the 9 that mentioned a self-reported impact factor, the median was 0.24 which means they had less than one citation per article in the last two years. The median publication fee for the 88 journals posting the information was $755.
Emails from the publishers contained a mean of 9.6 grammatical errors, possibly because more than half had addresses in foreign countries, and of those with US addresses, 30% were residential.
