2. Fig 1
Risk adjusted cumulative sum (Cusum) curves demonstrating three distinct patterns of performance for major morbidity at centers performing video-assisted thoracic surgery lobectomy. In these plots, an increment (upward spike) represents a failure, whereas a decrement signifies a success. The plots show three individual participants from the highest-volume group.
