Template of Lymph node stations used in the region-based analysis. This figure shows the template of the lymph node (LN) stations examined in this study. The iliac left and right region included all LN around the common iliac and external iliac artery. The obturator left and right region included all LN around the internal iliac artery and its branches. The presacral region defined the area anterior of the sacrum without strict allocation to vessels. LN of the inguinal region were defined below the inguinal bands.
