    Snippet: Data were analyzed using SPSS 20 software (SPSS for windows, IBM Corporation, Armonk, NY, USA). Continuous variables were reported as mean ± SD and categorical variables as number and percentage of each group. Variables were analyzed by comparison between the two groups (readmission and no readmission). Continuous variables were compared using a Student's t-test or Mann-Whitney test. Categorical variables were compared using a chi-squared or Fis.....
    Document: Data were analyzed using SPSS 20 software (SPSS for windows, IBM Corporation, Armonk, NY, USA). Continuous variables were reported as mean ± SD and categorical variables as number and percentage of each group. Variables were analyzed by comparison between the two groups (readmission and no readmission). Continuous variables were compared using a Student's t-test or Mann-Whitney test. Categorical variables were compared using a chi-squared or Fisher's exact test; Fisher's exact test was used when the expected number of events was ,5.
