Figure 2
Dark gray lines stand for negative binomial CUSUM score for unit sales of Iodine based antiseptics, homeopathic remedies and nutritional complements (from top to bottom).
The straight lines on the plots illustrate the threshold for the CUSUM score, defined as the maximum value of the CUSUM score in 2010. An increase in the CUSUM score indicates a strong positive deviation from the normal trend. Light gray lines represent unit sales volumes. Panel A shows results for all type of sales while panel B only shows sales with a physician prescription.
