Public Health data - GP recorded conditions Leeds

Directly Age Standardised Rates (DASR) per 100,000. Age standardised rates compensate for differing age structures by weighting them to meet the European Standard Population (2013). Rates can then be compared for different areas, or even across area types. Attention should be given to upper and lower 95% confidence intervals as a quick method of determining whether rates could overlap or are significantly different. Wide confidence intervals are indicative of small numbers in the numerator or of very skewed age structures. Rates of course cannot be summed, and because they are age standardised cannot be reverse engineered back to counts without knowing the age of every patient in the data when their condition was recorded.

直接年龄标准化率（DASR）每10万人。年龄标准化率通过加权调整以符合欧洲标准人口（2013年）的年龄结构差异，从而补偿不同地区或区域类型之间年龄构成的差异。比较不同区域或甚至不同区域类型的比率时，应注意上下95%置信区间，作为快速判断比率是否存在重叠或显著差异的方法。宽泛的置信区间表明分子中的数值较小或年龄结构极不均衡。当然，比率不能相加，并且由于它们是年龄标准化的，无法在没有了解数据中每位患者在记录其状况时的年龄的情况下，逆推回计数。
