Table 2. The Effect of Progesterone on the Serum Level of Intercellular Adhesion Molecule-1 (pg/ mL) in Diffuse Axonal Injury Patients.

Times	Control (n = 16) mean ± SEM, pg/ mL	Progesterone (n = 16) mean ± SEM, pg/ mL	P Value
Admission time	829.47 ± 93.31	990.52 ± 83.2	0.21
24 hours after injury	1422.96 ± 203.87a	868.97 ± 166.54b	0.04
6 days after injury	865.81 ± 193.61	939.61 ± 151.55	0.77

^aP < 0.05 vs. admission in the control group.

^bP < 0.05 vs. control group at 24 hours after the injury.
