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.
