Table 2 Number of lymph nodes dissected and labeling outcomes in the nano-carbon and control groups.
| Item | Nano-carbon labeling group (n=100)* | Control group (n=100)* | P-value | Mean/risk difference (95% Confidence interval) |
|---|---|---|---|---|
| Number of dissected lymph nodes | 18.75±4.21 | 17.10±5.03 | 0.045 | MD=+1.65 (0.04–3.26) |
| Number of labeled lymph nodes | 14.32±3.12 (1432/1875, 76.4% overall) | 8.20±2.85 (820/1710, 47.9% overall) | <0.001 | MD=+6.12 (5.1–7.1) |
| Labeling success rate | 76.35%±9.87% | 48.10%±10.25% | <0.001 | RD=+28% (23%–33%) |
| Number of non-labeled lymph nodes | 4.43±2.09 | 8.90±3.25 | <0.001 | MD=−4.47 (−5.3 to −3.6) |
| * Data are presented as mean±standard deviation unless otherwise indicated. MD – mean difference; RD – risk difference. | ||||
