In Aabel, the Bland & Altman method for comparing two methods of measurement or two paired variables provides:
- A plot of differences vs. mean
- A plot of differences as a % of averages vs. mean
- A plot of ratios vs. mean
- Aabel has the option of showing:
- The ±1.96 standard deviation, which is commonly used in a typical Bland & Altman plot

- A paired t-test difference plot with the 99% CI of mean difference above and below the mean line
