- Normally-distributed data are presented as mean ± standard deviation and analysed by Student’s t-test. Variables that were not normally distributed are presented as median and 25–75% percentile (in parentheses) and analysed by the Mann–Whitney test. The χ2 test was used for testing relationships between categorical variables. Bold text indicates a statistically significant p-value
