This is a very important thing to consider when interpreting this statistic. "Heart attack rates go up 24% after daylight savings changes" is not the same thing as "There are 24% more heart attacks due to daylight savings". You can't really know the weight of magnitude vs distribution without actually stopping daylight savings.
