Table 3: Postoperative changes in performance status, durations of hospital and ICU stay, and ED presentation after meningioma resection. Diabetics are at increased risk of postoperative deterioration, lengthier hospital and ICU stays, and present to the ED postoperatively at a higher rate than non-diabetics.
