The association between a free medicine program and functioning in people with schizophrenia: a cross-sectional study in Liuyang, China.

However, better refill adherence was not associated with better functional outcomes in this study, which might have been the result of reverse causation. To improve the effectiveness of the FMP, patient-centered measures should be considered.
