2.7. Statistical analysis
Statistical analysis was performed using SPSS (SPSS 20.0 for Windows,
SPSS Inc., USA). Normal distributions were checked by Shapiro–
Wilk test and homogeneity of variances by Levene test. The existence
of significant differences among the different phage therapy conditions
was assessed by one-way analysis of variance (ANOVA) model with the
Tukey post-hoc test. For each situation, the significance of the differences
was done by comparing the results obtained in the test samples
after correction with the results obtained for the correspondent control
samples (difference between the control and the test sample) for the
different times of each of the three independent assays. A value of
p b 0.05 was considered to be statistically significant.
