Agreement coefficient†, i.e., degree of agreement among raters by stakeholder groups (public health researches vs. public health practitioners) for each criterion and t-test whether the difference between stakeholder groups is statistically significant. Criteria S1 to S3 are the assessment criteria for the substantive research topics. Criteria M1 to M3 are the assessment criteria for methodological-theoretical research topics
†Interpretation of coefficient: 0.0–0.20 = slight agreement; 0.21–0.40 = fair agreement; 0.41–0.60 = moderate agreement; 0.61–0.80 = substantial agreement; 0.81–1 = almost perfect agreement
††T-test to investigate the difference between stakeholder groups
