### Index Analysis of Gait in Patients with CP
The results of [PERSON]'s correlations between the values of the GKI and GGI, as well as the GDI, in the group of patients with CP are presented in Table 8. All red-marked correlation coefficients (Table 8) are statistically significant (\(p<0.05\)), which means that, similar to the case of the reference group, we can reject the zero hypothesis about the lack of dependence between the analyzed indices. On the basis of the results of [PERSON]'s correlations, it can be stated that all selected indices strongly correlate with one another. A strong, statistically significant linear dependence was found between the values of the GKI, GGI and GDI in the group of patients with CP. The described dependences are presented in scatter plots in Figures 3 and 4. Below the scatter plots are the equations of a simple linear regression with a coefficient of determination R2. \begin{table}
