Patient baseline characteristics: well balanced between the robotic and laparotomy groups
| Variable | Total (n=135) | Robotic surgery (n=77) | Laparotomy (n=58) |
| Age, median (range), year | 63 (40–89) | 64 (40–89) | 63 (48–83) |

| Time interval between surgery and adjuvant RT, median (range), days | 77 (22–187) | 85 (46–187) | 66 (22–125) |
| LN dissection, n (%) | 107 (79.3) | 66 (85.7) | 41 (70.7) |
| Number of LN sampled, mean±SD | 9.1±5.0 | 8.8±4.9 | 9.6±5.1 |
| HIR patients, number (%) | 61 (45.2) | 36 (46.8) | 25 (43.1) |
Differences between the two groups were not statistically significant across all variables (p=ns). (If two of the three criteria are met: age 60 years or older, >50% myometrial invasion, grade 3).
EBRT, external-beam radiotherapy; HIR, high-intermediate risk; LN, lymph node; LVSI, lymphovascular space invasion; RT, radiotherapy; VBT, vaginal brachytherapy.
