Clinical states and transitions in <i>SDHB</i>-mutation carriers.

Transition probabilies are provided in the Tsdhb matrix, with 4 rows and 4 columns, upper right. Numerical values for steady states and transition probabilities are displayed here and also given in Table 1 and Table 2. For example, p12 is the probability of moving from state 1 to state 2 and p11 is the probability to stay in this state 1.
