Debugging MEDIASTINET with OpenMarkov. Two evidence cases are displayed in OpenMarkov: the prior case (colored in red), in which no evidence has been introduced, and an evidence case in which the CT scan is positive and the TBNA is negative (colored in blue). Evidential nodes are colored in gray. Bars in each node indicate the posterior probability (chance or decision nodes) or the expected utility (utility nodes) of the corresponding evidence case
