Nearly 20 years of cumulative follow-up of the Women's Health Initiative (WHI) Dietary Modification trial turned up something new. For the first time there was a significant reduction in deaths due to breast cancer in the dietary intervention group

"But as modelers, we have a responsibility. We have to be humble. We must make sure that the key caveats and uncertainties that are the nature of our work find their way into the headlines and are not relegated to the fine print." – Ruth Etzioni, affiliate professor of biostatistics and Fred Hutch researcher
Many of us trust the tests we take, and believe the yes-or-no results they return, writes Affiliate Professor of Biostatistics and Fred Hutch researcher Ruth Etzioni. But we need to be more curious. In the fraught deliberations about the optimal path to re-opening the U.S., one theme that has emerged louder and clearer than any other: testing, testing, testing.
"If I had to put my nickel on it, we don't have very high herd immunity in this population currently," said Elizabeth Halloran, a professor of biostatistics at UW and a biostatistician at Fred Hutch. "What we've done is reduce our transmission, and every model shows that if we open things up now, we will just have a rebound."
As we face critical decisions about whether and how to resume our daily lives in the midst of the COVID-19 pandemic, we are being tempted into making the wrong comparisons writes Affiliate Professor of Biostatistics and Fred Hutch researcher Ruth Etzioni.
Affiliate Professor of Biostatistics and Fred Hutch researcher Ruth Etzioni writes that not all COVID-19 models are created equal. There are key differences between the models that are currently being used to guide the national conversation — differences that should be understood by the public.
A recently-released study found that while travel bans have been useful in slowing the spread of coronavirus, social distancing measures have been far more effective in controlling the epidemic. “Delaying is good because it slows things down,” said the study’s co-author Elizabeth Halloran, a UW professor of biostatistics. “But this idea of reducing the transmissibility is really key.”
This interactive graphic was created using the data and expertise of Professor of Biostatistics Betz Halloran and others. It analyzed the movements of hundreds of millions of people to show why the most extensive travel restrictions to stop an outbreak in human history haven’t been enough.
