Mean and standard deviation are reported for each variable. Data from the whole sample are reported in the second column. In the third and fourth column, there are data from patients with (PN +) and without (PN−) personal neglect, respectively. PN = personal neglect; Std. dev. = standard deviation; AHP = anosognosia for hemiplegia; DSO = disturbance relating to the feeling of ownership of the affected body part; LUL = left upper limb; MRC = Medical Research Council Motricity scale. In the PN + group, 44 patients fail in both the line bisection and line crossing tests (Wilson et al. 1987), 21 only in line bisection, 3 only in line crossing and 5 do not suffer from extrapersonal neglect. In the PN− group, 15 patients fail in both the tests, 7 only in line bisection, 2 only in line crossing and 8 do not show extrapersonal neglect
