This story about a study of mammography in Swedish women in their 40s puts the findings in the context of other recent reports and highlights the critiques of independent experts, thus helping readers to see that this is just one more piece of the puzzle. By including the number of women that needed to be screened in order to prevent one breast cancer death, the story gives readers a more realistic perspective on the percentage difference in death rates the researchers saw between areas that screened younger women and those that did not.
A percentage difference that sounds dramatic may look much different when put into the context of the baseline risk and the potential drawbacks of an intervention.
The story only said once that "the costs are high" referring to screening and the risks of false positives and invasive procedures associated with them. We look for a bit more detail than that. But because it was the only story we reviewed that even mentioned costs, and becasue it reported that even this study indicates that over a thousand women would need to be screened for a decade to make a difference for one, we give it a satisfactory score.
This story reports not only the percentage difference in breast cancer deaths between the regions where women were routinely screened and where they weren’t, it also gives readers the total number of deaths and it highlights the finding that about 1250 women would need to be screened for a decade to prevent one breast cancer death.
The story also pointed out that the study did not report true breast cancer mortality rates – meaning how many women diagnosed with breast cancer died of it.
The story notes that screening can lead to false alarms and other adverse outcomes. Although it does not go into detail on the adverse outcomes, it includes comments from independent experts that the study failed to include the harms of screenings as well as the benefits.
The story provides an overview of the key features of this study and includes critiques from independent experts. Indeed, the story highlights concerns about the study design near the top of the story. (It could have done much more on this issue. For example, see our blog post on this matter.)
This story highlights both the total number of deaths reported by the researchers and the number of women who would need to be screened in order to prevent one death, thus putting the risk in perspective.
This story includes critiques of the study design and conclusions, although it does not identify or quote the independent experts, except for one neutral summary quote. (Why are these other critics named?) Although potential conflicts of interest are not reported, the researchers did not disclose any conflicts in their journal article. We’ll give it a barely satisfactory score, although the unnamed critics issues bothers us.
The story does not go into detail about alternatives, but it does highlight a guideline report from the United States Preventive Services Task Force that questions the value of screening mammography for women in their 40s, thereby implying that not being screened is an option.
There was no explicit discussion of mammography, but we can’t criticize the story for that. Nonetheless, we can only give a score of Not Applicable on this criterion.
The story does a good job of putting this study in context with other reports.
The story does not rely on a news release.
Systematic, Criteria-Driven
We’ve written about the hype of liquid biopsies for years (see link in comment below). And now this…. https://www.statnews.com/2022/01/12/medicare-shouldnt-cover-liquid-biopsies-early-cancer-detection/
Case counts still matter. “(There) are stories that may not be told adequately if only hospitalizations and deaths are emphasized.” @garyschwitzer interviewed by @dbauder of @AP. https://apnews.com/article/omicron-changing-news-outlets-covid-data-da9272f7c4c8a109c3bfb56bed9e9c76
My friend Gary @garyschwitzer wrote to his city council representative in a Minnesota town about a Viva Las Vegas event scheduled for January.
The response he got seems to perfectly capture where we are now.
