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.
