Statistical analysis
Data analysis was performed with commercially available software (IBM
SPSS version 20.0). Shapiro-Wilk test was used for normal distribution
of data. The data were statistically analysed by paired T-test to
compare the concentration of cardiac biomarkers, echocardiographic
indices and electrocardiographic parameters in horses before and after
exercise. The confidence interval percentage and the significance level
were 95% and p<0.05 respectively.
