Left to right, top to bottom rates of attainment of: a) the National Comprehensive Cancer Network (NCCN) recommended examination of at least 1 N1 lymph node; b) ≥3 mediastinal nodal stations; c) the aggregate NCCN surgical resection quality criteria; d) the Commission on Cancer (CoC) quality surveillance criterion (a minimum of 10 examined regional lymph nodes in stage IA-IIB resections). Horizontal bars indicate significantly different rates of attainment between intervention groups after Tukey adjustment for multiple comparisons (alpha=0.05).
