Statistical analysis
PCT
Data normality was assessed by means of Q-Q plots and the Shapiro Wilk test. Normal distribution was approved for all values; therefore, data were presented mainly using mean and standard deviation in addition to median, minimum, and maximum values. Repeated Measures of 2-Way ANOVA were made and then followed by pairwise comparisons with Bonferroni correction was performed to assess the matrix type effect, time, and the interaction between them on PCT. Using One-Way ANOVA, Tukey’s post hoc test, and Bonferroni correction, PCT values were compared between groups before and after the intervention. Meanwhile, for comparisons within groups, a paired t-test was conducted. Data were analyzed using IBM SPSS software package version 23 (IBM Corp., Armonk, NY, USA). The significance level was set at p value ≤ 0.05.
