Flus mutate so fast, Dr. Fukuda cautioned, that announcing each change is "like reporting changes in the weather".
It is difficult to determine the extent of such reporting changes from the aggregate data, but the change in overall prescriptions is interesting even if it to some extent reflect reporting changes as opposed to real changes in prescription behaviour.
Further, while d' can capture perceptual sensitivity to information it does not necessary represent the higher-level cognitive processes that would influence errors reporting changes in the type of complex stimuli presented in change deafness tasks.
For this question, there is a fairly high level of change over the course of the activity, with four pupils reporting changes on the Likert scale in the direction opposite to "improvement", and three in the direction of "improvement" (Table 1).

While our project was underway, papers were published reporting changes in DNA methylation of the HOX A Gene Complex associated with breast cancer [32], [33].
Clearly, reporting changes introduce distortions into case notification trends, and we chose to perform our analyses both with and without countries with known changes to minimize arbitrary changes in the series.
Since WHO does not systematically report on changes in reporting modalities, it is impossible to exclude the possibility that reporting changes in other countries may be affecting our results; however, this would result in upward bias, not downward bias, and thus would not explain our finding that DOTS has no effect on case detection.
