*

Baseline consumption for all participants or for least intensive intervention groups only when baseline consumption data not reported for all participants.

**

Baseline consumption in studies where 1 DR=10gr of ETOH recalculated to approximate the alcohol content of US studies (12–14gr of ETOH).

Studies varied in their assessment of drinking levels because the definition of a standard drink varies internationally. Many earlier studies from outside the United States 116 118 defined a standard drink as 10 grams alcohol (1 unit), while more recent US studies defined a standard drink as somewhere between 12–14 grams of alcohol or about 0.5–0.6 oz of alcohol. 111, 120, 122, 124, 127 The WHO International Study defined a standard drink as 14 grams of alcohol. Some did not explicitly define a standard drink, 126 and so were assumed to use the same standard as other studies from the same country for calculations comparing baseline consumption across studies.
