Table 2.

One-way ANOVA of Erlenmeyer flask deformity severity against volume and width ratios. Ratios with non-overlapping confidence intervals are in italics. Tukey’s HSD is reported with “EFD 0/1” representing the comparison between groups with EFD Severity Rating 0 and EFD Severity Rating 1, and similarly for the “EFD 0/2” and “EFD 1/2”
