Table 1 Within each volume stratum, the Kolmogorov-Smirnov test was used to discern potential differences between lymph node status groups for each of the heterogeneity metrics

From: FDG uptake heterogeneity in FIGO IIb cervical carcinoma does not predict pelvic lymph node involvement

Volume (in cc) Shannon entropy ( S) Sphericity ( ψ) Spherical extent ( ξ)
4.0 ≤ V < 22.4 D = 0.227; p = 0.886 D = 0.355; p = 0.390 D = 0.200; p ≤ 0.985

  1. The relatively high p-values implies that none of the metrics differ significantly across lymph node status groups.
