Interval-based data were examined for normal distribution with the Shapiro-Wilk test of normality and by visual inspection of the related histograms and p-p-plots.
All continuous variables were examined for normal distribution and a logarithmic transformation was applied for plasma triglycerides and glucose.
Continuous variables were examined for normal distribution.
All numerical data were examined for normal distribution.
Each variable was examined for normal distribution by the Kolmogorov-Smirnov equality of distributions test.
Before further analysis, each variable was examined for normal distribution by histogram and box plot.
All data were examined for normal distribution using the Shapiro-Wilk test.
Data was examined for normal distribution with a one sample Kolmogorov Smirnov test.
Each variable was examined for normal distribution, and the skewed variables were tested after logarithmic transformation.
All data were examined for normal distribution using normal Q-Q plots and the Shapiro-Wilk test.
All data were examined for normal distribution (Kolmogorow-Smirnov test) and subsequent tests were applied as appropriate.
