Figure 1. Probability of relapse by average care coordinator caseload.

This plot illustrates the cumulative probability of relapse over time (in days) when care coordinator caseload is varied for an otherwise ‘typical’ Early Intervention in Psychosis (EIP) patient. This typical patient is defined as having mean age and the most prevalent characteristics across other variables (e.g., Male, White, Unemployed, in receipt of CBTp etc). Survival times were probabilistically simulated using parameterized hazard rates for each group from a Cox proportional hazards model (with relapse probabilities increasing only at discrete event times) reflecting the plausible time-to-relapse patterns from the real population.
