Table 3 Univariate analysis of the detection of lymph nodes around the PGA in 39 patients with the PGA
Clinicopathological factors | Detected lymph nodes around the PGA | Did not detect lymph nodes around the PGA | Z or t | P-value |
|---|---|---|---|---|
Longitudinal tumor diameter [cm, \(\overline{X}\pm S\)] | 5.3\(\pm\)2.7 | 3.9\(\pm\)2.5 | t=-1.6 | 0.109 |
Total number of dissected lymph nodes [n, M (P25, P75)] | 30.5 (26.3, 43.5) | 26.0 (13.0, 31.0) | Z=-2.3 | 0.022 |
Total number of metastatic lymph nodes [n, M (P25, P75)] | 1.0 (0.0, 5.8) | 0.0 (0.0, 3.0) | Z=-1.1 | 0.290 |
Length of the PGA [cm, \(\overline{X}\pm S\)] | 3.5\(\pm\)0.9 | 3.5\(\pm\)0.8 | t = 0.1 | 0.922 |
Distance from the root of the PGA to the celiac trunk [cm, M (P25, P75)] | 7.0 (6.0, 7.9) | 7.0 (5.5, 7.5) | Z=-0.3 | 0.754 |
