2.6 Statistical analysis
All data analyses were performed using SPSS version 23.0 software. A
descriptive analysis was conducted on patient’s demographics, diseases
characteristics, types of DRPs, and recommendations. Comparisons between
the pre-intervention group and post-intervention group with regard to
clinical outcomes were given. Continuous data was computed with mean ±
standard deviation. Categorical variables were calculated with
frequencies and percentages. Groups were compared by Student’s T test
for continuous variables, by the Mann-Whitney test for continuous
variables with non-parametric distribution, and by the chi-square test
or Fisher’s exact tests for categorical data. Univariate analysis and
multiple linear regression were used to determine factors related to the
number of DRPs. A P value of <0.05 was considered to be
statistically significant.
