In addition to differences in the neck, skulls vary in size and shape between the two groups, though all are made up of the same bony elements.
Comparisons between all groups were made using the Kruskal-Wallis test.
In all groups, transcriptions were made in English (using the interpreter's real-time translation in the Turkish and Arabic speaking groups).
Instead, all group decisions were made through long discussions until all who cared came to an agreement.
Statistical comparisons of variance and mean values for all three groups were made using one-way ANOVA and post hoc Tukey test by Statistical Package for the Social Sciences (SPSS, Version 21, IBM co).. Paired t tests were also used to compare the distances between right and left side, and the maxillary occlusal cants to other measurements.
All group comparisons were made with the Mann-Whitney test.
All comparisons between groups were made on sections hybridized together, under identical conditions and exposed for the same periods of time to β-Max film (VWR, Sweden).
All comparisons between groups were made on sections hybridized together, under identical conditions and exposed for the same time period to β-Max film (Amersham, NJ, USA).
To avoid inter-treatment bias, the tissue slides from all the six groups were made on a single slide and subjected to the same immuno-staining simultaneously.
Not all girl-group records were made by groups.
For the main analysis, all treatment group comparisons were made using (a) Kaplan-Meier survival analysis (log-rank test), (b) Cox Proportional Hazards regression model, and (c) propensity score-adjusted bootstrap resampling method with 1000 iterations.
