(A) Construct validity: competency assessment of novices and experts using competency cumulative sum (C-CUSUM) test (graphs), and comparison of clinical outcomes of the first six cases of novices and experts using the group splitting method (table). (B) Criterion validity: learning curve assessments of novices and experts using learning curve CUSUM (LC-CUSUM) test (graph).
