  1. Classification of ADRs ADRs were classified according to the Naranjo, Schumock & Thornton and Hartwig & Siegel scale
  2. *The comparison between ADR group and without-ADR was significant (P < 0.05; Chi-square)
  3. +The comparison of hospital stay between ADR group and without-ADR was significant (P < 0.05; U Mann-Whitney)
  4. ADRs Adverse Drug Reactions
