Comparative StudyPublication bias in five dental implant journals: an observation from 2005 to 2009.
This study evaluated possible publication bias and its related factors in implant-related research over time. ⋯ There were a high number of implant-related studies reporting positive outcomes in the five selected journals. Some selected factors were associated with positive outcome bias. In general, funding was not associated with a positive outcome, except for animal studies. Industry-supported research did not show any association with the publication of positive outcomes.
