Dichotomized Glasgow Outcome Scale scores for patients receiving either progesterone or placebo. There was a remarkably more favorable outcome among patients who were given progesterone compared with patients receiving placebo (P = 0.034) 3 months postinjury. At 6-month follow-up, the significant difference in the dichotomization of Glasgow Outcome Scale scores between the progesterone and placebo groups was similar to that after three-month injury (P = 0.048).
