Metric Options: CountsSelecting 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
National mortality registers provide important data for monitoring population health. Analyses of cardiovascular mortality in particular—and especially mortality from coronary heart disease—are frequently the basis for conclusions about the quality of healthcare and prevention. To be able to interpret disease-specific mortality differences between countries and changes in mortality over time, it is necessary to know the basics of monocausal cause-of-death statistics and the associated limitations in comparative statements. Conclusions from disease-specific mortality data can be problematic due to the highly subjective selection of diseases that are entered on a death certificate after a post-mortem examination. In death certification, unawareness of the different “roles” of specific diseases—known at the time of death—within the causal chain leading to death can result in incomplete death certificates as a data basis for mortality statistics. Comparisons of disease-specific mortality rates are difficult due to different proportions of non-informative—including unknown—causes of death and due to country-specific preferences for which diseases are recorded on a death certificate—especially in the prevalence of multimorbidity. A population’s morbidity is therefore only reflected to a limited extent by mortality rates. Conceptual ambiguities with regard to the concepts of lethality and mortality when describing mortality rates can also lead to erroneous conclusions. Training of medical staff on how to complete a death certificate and the introduction of an electronic death certificate can improve the quality of mortality data. Irrespective of this, knowing potential pitfalls when analyzing mortality data will improve the quality of health reporting.
