From: Simultaneous versus video counting of coughs in hypertonic cough challenges
The Bland-Altman plot for CCR, the index that was used to express cough sensitivity in hypertonic histamine challenge. The difference between video vs. simultaneously counted, log-transformed CCR 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.
