Maybe I'm biased, but I have lower trust for studies with results like that.<p>Alcohol obviously reduces anxiety short-term, because of its effect on GABA signalling.<p>Alcohol can excarbate anxiety in long-term.<p>But there is catch - there are therapeutic drugs that have similar effect, benzodiazepines. Benzodiazepines can be misused (and make recovery from anxiety harder) and can be used for therapeutic purposes to improve patient's quality of life.<p>Obviously, benzodiazepines are more selective (ethanol affects nearly every system in brain), but I would expect that moderate and rare drinking to cope with single stressful event can be moderately beneficial, but drinking to deal with "stressful live" would be heavily detrimental.
