The authors identified 810 947 hospitalisations with an admission diagnosis of stroke during the time period between 2000 and 2009 in Taiwan. The ARIMA method (Auto-Regressive Integrated Moving Average) was used to examine the associations between ADS episodes and the daily number of stroke hospitalisations.

There were 46 separate ADS episodes which resulted in a total of 135 ADS days between 2000 and 2009. The Kruskal–Wallis test revealed that there was a significant difference in the mean number of daily stroke admissions among ADS days (239.6), post-ADS days (249.2) and non …
