Table 4 Equation applied for statistical evaluation

\(t=\frac{\overline{{x }_{1}}-\overline{{x }_{2}}}{\sqrt{\frac{{s}_{1}^{2}}{{n}_{1}}+\frac{{s}_{2}^{2}}{{n}_{2}}}}\)	t: t-value
	\(\overline{{x }_{1}}\): Mean value of the first group
	\(\overline{{x }_{2}}\): Mean value of the second group
	\({n}_{1}:\) Size of the first group
	\({n}_{2}\): Size of the second group
	\({s}_{1}\): Standard deviation of the first group
	\({s}_{2}\): Standard deviation of the second group
