The Kruskal–Wallis omnibus test of the scales on discipline categories revealed significant differences for the Quality of Recommendations and Support Evaluation scales (χ2 = 15.46, p = 0.004; χ2 = 13.65, p = 0.009). Dunn–Bonferroni tests of post hoc pairwise comparisons in particular indicated that researchers from the Engineering category had significantly higher mean ranks for the Quality of Recommendations scale scores than did researchers from the Social Sciences category (p = 0.002; see Fig 4). In addition, researchers from the Engineering category had significantly higher mean ranks for the Support Evaluation scale than did researchers from the Humanities category (p = 0.036; see Fig 5).
