A paired sample t-test and two alternative nonparametric tests: the sign test and the Wilcoxon signed rank test, have been utilized to determine if the difference in mean squares error between before and after the first 10-K filing was significant.
The road sign test was earlier conducted manually in the CTP headquarters.
We used the sign test and the Wilcoxon test because they are robust when using fewer than 20 polymorphic loci.

Baseline values and post-treatment values of the pain, disability and functional impairment parameters using KGMC score in each groups were compared using Wilcoxon sign test. Comparison between the KGMC scores of the two groups was done using Mann-Whitney U test.
