Figure 6.

Composition of the Recurring abstraction (see Evaluation and ▶), defined as an interval of decreasing platelet values (PLT decr) occurring after the first interval of recovering platelets (First recovering) and overlapping an interval of platelet values less than 100,000/μL (PLT low). Intervals are illustrated as in ▶. Recurring intervals have the same endpoints as the contributing PLT decr interval (gray dashed arrows). Gray dotted arrows denote temporal relationships defined between endpoints of intervals and are labeled with minimum and maximum time constraints. For example, (0, ∞) indicates that the second time point in the relationship must occur on or after the first point (∞ = largest possible time distance). This type of abstraction is recognized by the temporal pattern high-level abstraction mechanism (see Design).
