Figure 1.

EventFlow plots of pediatric (A) and adult (B) giardiasis event sequences. All sequences (rows) are aggregated by event order, with each patient's first event during the study window represented by a vertical bar at the far left. Bar height represents the proportion of patients with a given sequence, and bar shading represents event type. Distance between bars is equivalent to median time in days between any 2 events. Three Giardia-specific event types are shown: Giardia-specific tests (black), antiparasitic prescriptions (dark gray), and antibiotic prescriptions (light gray). Most but not all cohort patients had at least 1 of these 3 events. Therefore, plots show pediatric (n = 782; 86%) and adult (n = 1808; 87%) sequences containing any of the 3 events. Time from first event (horizontal axis) is truncated to 60 days for clarity; 72% of all sequences had total elapsed time of ≤60 days. Starting from the left of the panels, we saw that more pediatric vs adult sequences started with a Giardia-specific test (black bars) and included multiple consecutive tests, whereas adult sequences were more likely to begin with an antiparasitic drug (dark gray bars).
