Multivariate logistic regression for odds of positive completion lymph node dissection
| Odds ratio | 95% Confidence interval | P value | |
|---|---|---|---|
| Before MSLT-II implementationa | 0.72 | 0.182–2.85 | .639 |
| BMI >30 | 2.56 | 0.678–9.75 | .167 |
| Location, head and neck | 0.33 | 0.060–1.80 | .197 |
| ≥3 positive lymph nodes at SLNB | 12.04 | 1.67–83.5 | .013 |
| Sentinel lymph node tumor burden > 1 mmb | 25.71 | 2.54–231 | .005 |
Abbreviations: BMI, body mass index; CLND, completion lymph node dissection; SLNB, sentinel lymph node biopsy.
The inflection point for implementation is based on an observation of trends in CLND by quarter after MSLT-II publication, Figure 1.
No CLND was positive for patients with sentinel node tumor burden < 0.1 mm.
