Path analysis of patients in the left hemisphere lesion group.
The results of the path analysis show that damage to the left AF posterior segment has a negative impact on the postoperative performance of the digit span forward. Additionally, damage to the left AF posterior segment affects KPS through the performance of the digit span forward, digit span backward, and MMSE. Note: Left AF posterior: disconnection ratio of the left AF fasciculus posterior segment; Left AF long: disconnection ratio of the left AF fasciculus long segment; MMSE, Mini-Mental State Examination; KPS, Karnofsky Performance Status; solid line, statistically significant; dotted line, not statistically significant. We omitted the influence of age on the digit span (forward and backward), MMSE, and KPS.
Fig 3.
Path analysis of patients in the right hemisphere lesion group.
The result of the path analysis shows a positive effect on premorbid IQ and a negative effect on damage to the right cingulum posterior part of the postoperative digit span forward. Premorbid IQ directly affects postoperative MMSE scores. Premorbid IQ and damage to the right cingulum posterior partly influence the KPS by mediating the digit span forward, digit span backward, and MMSE. Note: Right cingulum posterior: disconnection ratio of the right cingulum posterior part; MMSE, Mini-Mental State Examination; KPS, Karnofsky Performance Status; solid line, statistically significant; dotted line, not statistically significant. We omitted the influence of the age on the digit span (forward and backward), MMSE, and KPS.
