Osmolality of lumbar CSF obtained from iNPH patients selected for shunt surgery versus no surgery. a The osmolality of lumbar CSF (L-CSF) in iNPH patients not shunted (n = 15) versus those who were shunted (n = 20). The data were evaluated for statistical significance with the Mann–Whitney test. b The osmolality of iNPH patient CSF as a function of the outflow resistance measured during diagnostic workup, n = 11 shunted and 14 non-shunted patients. c Patient CSF osmolality plotted versus the resting ICP determined by lumbar infusion tests, n = 11 non-shunted patients and n = 12 shunted patients. NS not significant
