However, we should carefully use this kind of information, since publication bias. Publication bias arises because we often publish the significant results than non-significant conclusion, and hence, the published data are truncated by alternative hypothesis. It tends to give a tendency of over-estimate or under-estimate in a long run. In this paper, we propose a method of using simple linear regression model and maximum likelihood technique to adjust the publication bias while merging the truncated data under bridging study in order to make our estimation more efficient.
