From: Simultaneous versus video counting of coughs in hypertonic cough challenges
The Bland-Altman plot for CUM15, the index that was used to express cough sensitivity in hypertonic saline challenge. The difference between video vs. simultaneously counted CUM15 is plotted against the mean of the respective index. The solid horizontal line represents the mean difference between the two counting methods and the dashed lines the 95% limits of agreement.
