Statistical analysis
Continuous variables were expressed as mean ± standard deviation (SD).
Categorical variables were presented as numbers and percentages.
Comparison between normally distributed continuous variables was done
using paired sample Student’s t-test for paired samples and independent
sample t-test for independent samples; statistical significance was
achieved at a p-value, p < 0.05. Statistical analysis was done
using SPSS 24 software (IBM SPSS Statistics for Windows, Version 24.0.
Armonk, NY: IBM Corp). To determine the influence of protocol complexity
on the workflow efficiency, a sub-group analysis was performed to
compare the study duration and the total keystrokes between the “more
complex” MR protocol and the combined AF and AS protocol of “lesser
complexity”.
