Table 3. Differences in mean scores for reviewers from institutions in different geographical regions with respect to all other regions.

Tables shows data with uncorrected p<=0.05. * shows significant bias after application of the Bonferroni correction for multiple hypothesis testing (Frontiers α = 0.005; IEEE-Spain α < 0.0125; IEEE-International α < 0.0028).
