Table 5 Comparison between the two studied groups according to different parameters: margins and shape

From: Imaging of metastatic cervical nodes: is CT helpful in differentiation of squamous cell carcinoma (SCC) from non-SCC groups?

  SCC χ2 p
SCC (n = 94) Non-SCC (n = 63)
Outer margins/periphery of node
 Regular 73 (77.7%) 48 (76.2%) 0.046 0.830
 Irregular 21 (22.3%) 15 (23.8%)
Shape
 Rounded 80 (85.1%) 53 (84.1%) 10.307* MCp = 0.008*
 Oblong 4 (4.3%) 9 (14.3%)
 Oval 8 (8.5%) 0 (0%)
 Oval to oblong 2 (2.1%) 1 (1.6%)
