A case-crossover study of alcohol consumption, meals and the risk of road traffic crashes
<p>Abstract</p> <p>Background</p> <p>The case-crossover (CC) design has proved effective to investigate the association between alcohol use and injuries in general, but has never been applied to study alcohol use and road traffic crashes (RTCs) specifically. This study...
