Notes: Comparison of small-world parameters and network efficiency parameters between PD patients and HC groups. Both PD patients and HCS have small-world properties. Gamma and Sigma decreased in the PD group. (Two-sample t test, p < 0.05, Bonferroni corrected). Significance of values in bold indicates < 0.05 and corresponding t values.

Abbreviations: Cp, clustering coefficient; Lp, characteristic path length; Gamma, normalized clustering coefficient; Lambda, normalized characteristic path length; Sigma, scalar small world; Eglob, global efficiency; Eloc, local efficiency; PD, primary dysmenorrhea; HC, healthy control.
