Visuospatial performance and its neural substrates in Dementia with Lewy Bodies during a pointing task.

The group effect was highly significant, with patients exhibiting a higher mean error (mean accuracy controls = 0.64 cm±0.31 cm; mean accuracy patients = 4.69 cm±2.65 cm; β = 4.678±0.847, t = 5.522, p < 0.001), but no main significant effect of target position or interaction effect between group and target position was revealed (all p > 0.05).
