inference obtained by the clinical judgement of an expert's panel (named
global introspection) is the most universal used method for individual
causality assessment of adverse drug reports. Its internal validity lies on
the small probability of different results in the consensus obtained for
similar conditions, whilst its external validity remains to be studied.
Despite its usefulness, the global introspection method of causality
assessment has been subject to criticisms of subjectivity and imprecision
once it is mainly based on expert clinical judgements.
