When discussing epidemiological data we must consider the tools of assessment and the selection of the target population. As a rule, well designed population studies give us an accurate but crude picture of what is going on. What we gain in details with a more elaborate method we often lose when we want to generalise. Population studies in Göteborg have shown that the prevalence of dyspepsia is the same among men and women in the age groups between 30-70 years. After the age of 50 dyspepsia is less common. With the methods described, it was not possible to make a clear distinction between the ulcer dyspepsia group and the non-ulcer dyspepsia group except for smoking (which was more common in the ulcer dyspepsia group).
在讨论流行病学数据时，我们必须考虑评估工具和目标人群的选择。通常，设计良好的人群研究能为我们提供关于实际情况的准确但粗略的图景。当我们想要进行概括时，我们用更精细方法获得的细节往往会丢失。哥德堡的人群研究表明，在30至70岁年龄组中，消化不良在男性和女性中的患病率相同。50岁以后，消化不良就不那么常见了。用所描述的方法，除了吸烟（在溃疡型消化不良组中更常见）外，无法明确区分溃疡型消化不良组和非溃疡型消化不良组。
