Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A food frequency questionnaire consisting of seven categories of food types and 266 food items was developed for a dietary survey of the Hong Kong Chinese population. The quantity, frequency of consumption per day and per week for each item was recorded with the aid of photographs to illustrate portion sizes, and nutrient quantity calculated using Food Tables from multiple sources — UK and two mainland Chinese institutions. The validity of the nutrient quantitation was examined by comparing calculated 24 hour intake of total energy, sodium, and potassium, with estimated values of energy expenditure (BMR × 1.4), 24h urinary sodium and potassium outputs. Apart from probable underestimation of sodium and potassium intake, calculated values for energy were close to estimated values. Associations were also present between energy intake, cholesterol, fat, and fatty acid intakes, and serum lipid profile. It is concluded that this questionnaire is suitable for dietary surveys in Hong Kong Chinese and may be used for quantitation of nutrient intakes in studies examining dietary components as risk factors.
