What key aspect is typically evaluated in historical data reviews?

The key aspect evaluated in historical data reviews is often incidence completeness. This focuses on ensuring that all cases of cancer that meet specific criteria for a given timeframe and population have been identified and reported. A thorough review aims to ascertain whether any cases were missed, thereby affecting the overall quality and reliability of the cancer incidence data collected. Incidence completeness is crucial for understanding the burden of cancer in a population and for informing public health policies.

While data accuracy is also an important aspect of data collection, it is not the primary focus during historical data reviews. The primary goal is to assess whether the data adequately reflects the true number of cases diagnosed and reported, which aligns with evaluating incidence completeness. Therefore, the evaluation of historical data primarily emphasizes ensuring that the total incidence reflects all diagnosed cases rather than verifying the correctness of the individual data points within the collected dataset.
