Statistical Analysis
All statistical analysis was performed using SPSS v.17.0 software (SPSS Inc, Chicago, IL). Shapiro-Wilk test was used to check distribution of numerical values. Categorical variables were expressed with frequency and percentage values whereas numerical values were expressed as mean, standard deviation or median and min-max values. Chi-square test was used to analyze the relationship between two categorical variables. Non-parametric Friedman test was used to compare 2 or more consecutive MMT score mean values and Wilcoxon signed series test was used to compare two dependent score mean values. Independent sample mean values were compared using non-parametric Mann-Whitney U test. The difference between independent median measurements were assessed using non-parametric median test. Pearson Correlation Test was used to analyze the relationship between numerical values. All analyses were performed on a 95% confidence interval and p<0.05 values were deemed as statistically significant.
