  1. SD = Standard deviation. Maximum points on the iNPH-scale = 100 representing normal performance. Since the formula can be adjusted for the number of available domains, the total score was available for all patients despite missing data in individual symptom domains. D represents outcome scores total and for each domain, i.e. postop. score– preop. score. h = hours; SSCD = somnolence sopor coma disorder.
