IPQ of the lists versus IFa among participants (IFp) in the postings. CHILD-NEURO and PED-LUNG improved their potential quality (IFp much higher than IPQ). PEDI-OTO and PED-SURG-L showed IFp much lesser than IPQ. PEDNEPH, data not available in the study of subscribers.
Distribution of average IFp in each mailing list per number of postings per participant. In some lists (PICU, PEDS-UROLOGY) discussions were held by few of members with high publishing standing; others showed more uniform participation (PEDPATH, CHILD-NEURO).
Comparison of IFa among the lists and the pediatric journals. All the journals had a higher IFa among their first authors than the average impact factors of the participants on the corresponding mailing list. Nevertheless, CHILD-NEURO rated a higher value than some of the journals.
