Graph description: Sample size for a study of agreement between two methods of measurement, 2

The figure shows axes labeled "difference" on the vertical and "average" on the horizontal.
There are solid horizontal lines through mean difference and the two 95% limits of agreement.
For each of these horizontal lines, there are two other, broken lines for the confidence intervals
above and below.
The confidence intervals for the 95% limits of agreement appear much narrower than in the first graph,
and are well separated from the confidence interval for the mean difference.
