Table 2.

Results (mean ± sd) and comparisons in the two iterations of the Delphi exercise across the 17 criteria.

No statistically significant differences were identified between the two iterations at a Bonferroni adjusted alpha of 0.004. Criteria are colored to identify the three occupational health-and-safety pillars: contribution to improving occupational health (green), mitigation of worker physiological strain (blue), and cost-effectiveness (red). Key: d = Cohen’s d effect size; p = p value from two-tailed paired samples t tests comparing the two iterations.
