Risk of re-presentation to hospital. Cumulative probability of re-presentation for a all patients from episodes 1–3 and b only those infected with P. falciparum (red) and P. vivax (blue) species at each episode; the second to fourth columns correspond to episodes 1–3 and present the risk of re-presentation for the subsequent episode (i.e., transitions 1 → 2, 2 → 3, 3 → 4). Since the results of re-presentation were almost identical in Models (1) and (2), only the results of Model (1) are shown
