- Displayed is the number of instances, for each MTU group and all combined MTU, where the MTU quality evaluation metric was either (+) improved, (−) worse, or (±) no change. For each MTU group, sample size was 48 (8 MTU × 6 subjects). For all combined MTU, sample size was 144 (8 per group × 3 groups × 6 subjects). Statistically significant differences are denoted using coloured cells, where green indicates improvement, red indicates worsening, and yellow indicates no change. In cases of no statistically significant difference between any of the three types of results, cells were left unshaded
- +, Represents improvement from models 1–3; −, represents worsening from models 1–3; ± represents no change between models 1 and 3
