Group | Maximum Wall Stress (kPa) | Average Wall Stress (kPa) | Minimum Wall Stress (kPa) |
---|---|---|---|
N | 35 ± 4.0 | 26 ± 4.0 | 20 ± 4.0 |
E | 13 ± 1.0 | 8.0 ± 0.4 | 3.0 ± 0.2 |
P | 16 ± 0.5 | 10 ± 0.5 | 5.0 ± 0.3 |
p-value | 0.0002 ab | 0.0003 ab | 0.0002 ab |
a denotes significant pairwise differences across N and E groups and b denotes significant pairwise differences across N and P groups (repeated measures ANOVA—sphericity assumed).
