3) the occurrences of bone fracture (single + multiple) were 6.95%, 39.16% and 15.57% respectively, the value of Chi-square was 5.067, p = 0.079, indicating there were no significant differences exited among the three groups.
The averages of duration of the symptoms in the three sub-groups were 36.44 months, 52.95 months and 75.58 months respectively, the value of Chi-square was 17.299, p = 0.000, indicating significant differences exited among the three groups.
The averages of sites of pain or numbness in the three sub-groups were 2.80 sites, 3.50 sites and 3.24 sites respectively, Kruskal-Wallis test manifested that the value of Chi-square was 11.200, p = 0.004, indicating significant differences exited among the three groups.
All the results were got in vitro, while in vivo individual difference exits; oral environment is different from experiment environment, and not everyone would obey the instructions provided by doctors or instructors, so different results may be observed.
To some extent, it plays a key role in delaying the time and the breakage spacing of the main roof and mitigating the discontinuous and asymmetrical deformation and breakage, especially the scope of the stress-relief area, where a clear difference exits below and above the hard thick strata.
*: compared with non-OP group, significant difference exited.
However, significant differences exit.
Thus, differences in exiting student career preferences between medical schools are related both to capital [student variables] and habitus [variation in medical school education and culture] [ 45, 46].
