†A square-root transformation was applied to the dependent variable.
‡Comparison reference group ‘I am in neither risk category’.
§A ‘case’ is defined as a PHQ-9 Score greater than or equal to 10, at which level someone would qualify for high intensity psychological support in the National Health Service.
