Stoffels and coauthors compared metastatic node detection and disease-free survival using single-photon emission computed tomography/computed tomography-aided sentinel lymph node excision (SLNE) vs standard SLNE in 464 patients with melanoma from a single institution.
Colla and coauthors compared spending and outcomes between 10 practices participating in the Medicare Physician Group Practice Demonstration (n = 990 177) and local control practices (n = 7 514 453) before and during the demonstration using different risk adjustment.
