All statistical tests were 2-sided.
AC, adenocarcinoma; ASC, adenosquamous carcinoma; CCRT, concurrent chemoradiotherapy; FIGO, International Federation of Gynecology and Obstetrics; NS, not significant; PLN, popliteal lymph node; RT, radiotherapy; SCC, squamous cell carcinoma; SD, standard deviation.
*The Wilcoxon rank sum test was used to analyze continuous variables (age, tumor size, and the pretreatment hemoglobin level); †Fisher's exact test and the χ2 test were used to analyze categorical variables; ‡The median test was used to analyze continuous variables (the duration of RT).
