Performance of patients with INPH, as percentages of median performance in healthy individuals. Error bars indicate the interquartile range. To make impairments clear, results from tests with time scores were recalculated as units per time. Thus a lower score always mean impairment. The performance for the figure copy task is expressed as the ratio of correct response-ratios in the INPH and healthy groups. The INPH patients performed worse than healthy controls in all tests (Mann-Whitney, and Chi-square test for the figure copy task, p < 0.001).
