Data are represented as mean ± standard deviation.
All the data were measured in inches.
Independent t-tests were performed between the slot top and slot base because of the normality of the data.
Slot parallelism could be interpreted from the p-values.
One-way ANOVA was performed due to the normality of the data (p = 0.000, <0.05).
The results showed statistical differences between the groups (p < 0.05).
Tukey’s post-hoc test was performed; subgroups for α = 0.05.
The different characters represent the statistical differences.
***p < 0.001.
