PG  - 1058-62
AB  - There are 4 methods to determine a minimal clinically important difference (MCID) 
      currently, namely anchor-based method, distribution-based method, opinion-based 
      method, and literature review. The anchor-based method offers the clinical 
      significance of MCID, but it does not consider the measurement error. The 
      anchor-based method is limited due to difficulty to obtained a suitable anchor in 
      most cases, and variation of MCID with the anchor. The distribution-based method 
      takes measurement error into account, and is easily implemented. The 
      distribution-based method can not provide the clinical explanation of MCID, and 
      the MCID from different samples might differ from each other. There is no golden 
      criterion to judge MCID by distribution-based method so far. The opinion-based 
      method and literature review are based on the opinions of experts and the 
      published literature, respectively. They are usually regarded as a supplement to 
      anchor-based method and distribution-based method. It is suggested that 
      anchor-based method, distribution-based method, and opinion-based method should 
      be used together when determining a MCID.
