This will find if there is a big influence of publication bias and to give comparable statistics to this question a random sample of eighty-six references were taking from a database. The database was based on explanative and evaluation approach, which was more quantitative. While the second question was about the statistical assessment of publication bias that asked to what extent is a statistical assessment of publication bias for evaluation studies in health informatics possible (Machan, 2006). This question allows for a scatter plot classifying every single study by effect size and study quality. In order to achieve the researchers had to find a certain number of studies evaluating the systems, measuring the same effect and providing quantitative data for effect size and study quality. The evaluation research done for this question was physician order entry system, drug prescription system, and more quantitative. Whereas the third question was quality of reviews and meta-analyses that asked are there more systematic and narrative reviews or more meta-analyses referenced in the database and do most of them draw positive, neutral or negative conclusion (Machan, 2006).
