Application of
graph theory across multiple frequency bands in obsessive-compulsive disorder
Fig 1. Global properties of whole brain in
obsessive-compulsive disorder (OCD) and healthy control (HC) groups. The bars
showed significant between-group differences in the area under the curves (AUC)
of global metrics at slow2, slow3, slow4, slow5 and reference frequency bands
(0.01-0.08Hz). (a) γ, normalized clustering coefficient; (b) λ, normalized
characteristic path length; (c) σ, normalized small-world; (d) Global
efficiency; (e) Modularity, Q. * p<0.05, with t test. referB, reference
frequency band between 0.01 and 0.08 Hz.
Fig 3. The significantly
different nodal properties at slow3 band between the OCD patients and healthy
controls. (p<0.05, FDR corrected). (a) Degree centrality; (b) Betweenness centrality;
(c) Nodal clustering coefficient; (d) Nodal shortest path. Warm colors indicate
increase in OCD grooup, cool colors indicate decrease.
