Dealing with Publication Bias Publication bias has been defined as the tendency on the part of investigators to submit, or journal editors, to accept manuscripts based on the significance of findings. Publication bias iimplies that positive study results have a better chance of being published, are published earlier, and are published in journals with higher impact factors. Conclusions exclusively based on published studies, therefore, can be misleading, and yet, most systematic reviews rely on published studies. A number of reasons have been cited for publication bias, including: negative findings; failure of authors to submit manuscripts; rejection of manuscripts by journal editors. This poster presents ways in which to find and access those studies that have not been published, yet are important to determining best practice.
