Table 2.

Comparison of motor neuron survival in three experimental groups by Kruskal-Wallis test (n = 21). Intraperitoneal minocycline group has the highest motor neuron survival as compared to the sham and intrathecal minocycline group.

Variables	Experimental groups			Chi-square (df)	P-value*
	Sham group (n = 7) Median (IQR)	Intraperitoneal group (n = 7) Median (IQR)	Intrathecal group (n = 7) Median (IQR)
Motor Neuron Counts	14 (4)	19 (2)	12 (2)	14.40(2)	0.001

^*Kruskall-Wallis tests

Post hoc test with Bonferonni corrections by Mann-Whitney test:

Sham group versus Intraperitoneal group, P = 0.002 × 3 = 0.006 (< 0.05);

Sham group versus Intrathecal group, P = 0.093 × 3 = 0.279 (> 0.05);

Intraperitoneal group versus Intrathecal group, P = 0.002 × 3 = 0.006 (< 0.05)
