Similarly, the shortest path length was lower in grp‐E (left glioma, 3.880 ± 0.143; right glioma, 3.477 ± 0.213) than in grp‐nE (left glioma, 4.381 ± 0.066, p = 0.0041; right glioma, 4.308 ± 0.121, p = 0.0025) and grp‐GnE (left glioma, 4.456 ± 0.139, p = 0.0099; right glioma, 4.433 ± 0.119, p = 0.0014). Here, GRP is linked to central nervous system cancer.
