Revealed: NIH research grants still frozen despite lawsuits challenging Trump order Nature - The Trump administration is exploiting a loophole to keep a funding freeze in place, leaving researchers in limbo.

Almost all grant-review meetings remain suspended at the US National Institutes of Health, preventing the world’s largest public funder of biomedical research from spending much of its US$47 billion annual budget.

If you were taught to test for proportional hazards, talk to your teacher.

The proportional hazards assumption is implausible in most #randomized and #observational studies because the hazard ratios aren't expected to be constant during the follow-up. So "testing" is futile.

But there is more 👇

Climate change in the polar regions of our warming world is threatening to transform many of its features, such as this icy tableau in the Fish Islands off the coast of the Antarctic Peninsula. There is still much to learn about these places before we know better what those changes may be.

A new special issue of Science highlights research on Earth’s frozen places—from the Arctic to the Antarctic—and how it’s changing due to climate change and the geopolitical challenges this important work faces.

That "immortal time" is so frequent in survival analyses for #causalinference is fascinating.

Because "immortal time" doesn't exist in the data, *we* create it when misanalyzing the data.

Our new paper pubmed.ncbi.nlm.nih.gov/39494894/ summarizes why immortal time arises & how to prevent it.

Considering rural areas’ complexity in shaping health interventions | Harvard T.H. Chan School of Public Health There’s no one-size-fits-all definition of what constitutes a rural community in the U.S., but there are four distinct patterns of rurality, each with strengths and deficits upon which tailored health...

Our graduate student affiliate Jen Cruz led a study that analyzes different types of rural communities with the hope that we can use "this knowledge to build healthier, stronger rural communities." #HarvardChan
