Relationship between relative deviation and other journal impact factors (Scientific Journal Ranking (SJR), Eigenfactor (EF) and H factor). The fit of a linear regression and a local polynomial regression (dotted line) together with their 95% confidence bands are drawn for each impact factor. All regressions are adjusted for the weight that study results received in the meta-analysis, which is fixed at median value for plotting. Regressions are weighted with the respective impact factor to account for heteroscedasticity
