Models are multivariate (all predictors in each column entered at once) and based on a survival framework (with person-visit file); each column represents a separate multivariate model of dropout from care in that sector. Because the sample is restricted to those with 1–2 visits- it is not possible to have more than 2 providers.

For other mental health professions, the age categories are 18–59 vs 60 due to scarce data

Number of cases that received treatment from the provider
