A further limitation in our study is the use of age standardised portion sizes and not actual individual portion sizes.
Each participant was asked how often, on average, she consumed each type of alcoholic beverage over the previous year, using standardised portion of each beverage (a 12-oz bottle or a can of beer, a 4-oz glass of wine, or a 1.5-oz serving of liquor).
11 We standardised portions as a 12 oz (355 ml) bottle or can of beer, a 5 oz (148 ml) glass of wine, and 1.5 oz (44 ml) glass of 80 proof (40% alcohol) distilled spirits.
We standardised portions as a 12 oz (355 mL) bottle or can of beer, a 5 oz (148 mL) glass of wine, and 1.5 oz (44 mL) of 80 proof (40% alcohol) distilled spirits. 1 We categorised the volume of alcohol intake as <2.5 g/day (<0.5 drink), 2.5-14.9 g/daboutbout 0.5-1 drink), 15-29.9 g/daboutbout 1-2.5 drinks), 30-60 g/day (about 2.5-5 drinks), and >60 g/day (≥5 drinks).
At the first visit, all subjects will receive standardised information regarding healthy diet, portion sizes, regular meals and physical activity.
Although we standardised primary data using a standard portion size of 106 g, conclusions should be interpreted with caution.
We standardised all data using a standard portion size of 106 g, in agreement with other meta-analysis studies that have analysed fruit and vegetable intake and risk of chronic disease.
16 When some studies included in our meta-analysis used different measurement units (eg, grams per day or portions per day or servings per day), 5 10 15 we standardised fruit and vegetables intake into servings per day using a standard portion size of 106 g.
We standardised all data into servings per day, using a standard portion size of 106 g. 29 Any disagreement was resolved through discussion.
All questionnaires contained primarily completely standardised items that were identically worded as far as possible with a five-point response scale, along with a small portion of free-response questions.
Governments have set aside portions of the electromagnetic spectrum for the specific use of wireless telemetry, though these are not always standardised across international regions and there are severe bandwidth limitations and interference issues.
