Fig. 4From: Using Markov chain model to evaluate medical students’ trajectory on progress tests and predict USMLE step 1 scores---a retrospective cohort study in one medical schoolTransition probablities for all students based on all 10 NBME tests. Notes: 1. Each round Nodes indicates the range of NBME tests in each state. 2. The values on the arrowed lines/curves indicate the transition probabilities from one state to another stateBack to article page
