Screener are useful instruments for categorising individuals according to their nutrient intake. To accurately classify the individuals it is important to correctly analyse the screener. Therefore we compared a simple and a weighed score of a cholesterol and saturated fat (SF) screener with the cholesterol and SF intake, respectively, calculated from an extensive food frequency questionnaire. The validation results did not change when a weighed score was used instead of the simple one, indicating that a simple score does not introduce a higher amount of misclassification.
筛查工具是根据个体营养摄入量对其进行分类的有用工具。为了准确地对个体进行分类，正确分析筛查工具很重要。因此，我们将胆固醇和饱和脂肪（SF）筛查工具的简单评分和加权评分分别与通过广泛的食物频率问卷计算得出的胆固醇和SF摄入量进行了比较。当使用加权评分而非简单评分时，验证结果并未改变，这表明简单评分不会导致更高的错误分类率。
