Table 2 Associations between the Shields Index, the component measures, and subsequent metastases.

From: Prediction of melanoma metastasis by the Shields index based on lymphatic vessel density

  Metastasis at 5 yrs (n = 45) No metastasis at 5 yrs (n = 57) Odds ratio (95% CI) p
Mean lymphatic vessel density, vessels/mm2 (SD) 10.24 (5.54) 6.52 (3.82) 1.19 (1.08, 1.31) 0.001
Number with lymphatic vessel invasion (%) 38 (84) 26 (46) 6.47 (2.48, 16.90) <0.001
Mean Breslow thickness, mm (sd) 2.36 (1.55) 1.93 (1.37) 1.23 (0.93, 1.61) 0.15
Log shields index (sd) 2.43 (0.50) 1.77 (0.62) 9.86 (3.57, 27.24) <0.001
  1. The odds ratios are for a one unit increase in LVD, Breslow thickness and the log10 Shields Index, and for the comparison between patients with and without lymphatic vessel invasion.
