Back-transformed from transformed data. AD = antidepressant. BADDS = Bipolar Affective Disorder Dimension Scale. LT = lifetime. MHC = mental health component. PC = primary care. PHC = physical health component. PS = present state. UBD = unrecognised bipolar disorder. Appointment rate = number of appointments per year for a mental health problem.
