This is getting increasingly harder to understand, @RobertKennedyJr . In the America First era, when a U.S. federal agency wants to do a randomized trial, it sends $1.6 million to Denmark? I don't run trials, but so many excellent U.S. researchers do. Aren't they good enough?

Public health scientists are raising concerns following news of a $1.6 million award from the U.S. Centers for Disease Control and Prevention for a trial of hepatitis B vaccines in newborn babies in the West African nation of Guinea-Bissau. scim.ag/45iYgcx

OK quick thread about the stats fu involved in trying to sort out whether acetaminophen causes autism or not and some of our various misunderstandings. The excellent book recommended by @mbw61567742... x.com/mbw61567742/st…
Michael Weissman@mbw61567742

@PatrickSSte @gadboit @realZenelan You can stratify by any *potential* other cause to isolate the effect of the cause in which you're interested. Try reading Causal Inference in Statistics: A Primer. It's fun to learn, even for those of us past our prime.

I have a question for @RobertKennedyJr. You want to Make America Healthy Again. Exactly which year you’d like to go back to? 2007, 1992, 1983, 1976…? It’s hard to evaluate your policies without this piece of information. (Ok if a member of your staff replies)

2/ Immortal time may occur when individuals are 1) assigned to treatment strategies based on post-eligibility information or 2) determined to be eligible based on post-assignment information #TargetTrial emulation prevents it by synchronizing eligibility and assignment at time 0

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

@CAUSALab @HarvardChanSPH @HarvardEpi I’m so thankful that I could work side-by-side with Roger Logan for over two decades. He was a cornerstone of @CAUSALab. I learned a lot from him. Roger’s expertise and generosity will be very much missed.

This week I discussed methods for health technology assessment @HTAiOrg: "Observational data (#RWD) can often be used to emulate a #TargetTrial, but we need more research to characterize questions that can only be answered by randomized trials." Let's learn the limits of #RWE

The @TARGETGuideline team needs your help. If you work on #causalinference from observational data, please get involved in piloting the reporting guidelines for #TargetTrial emulation. Diverse viewpoints will make the guidelines more useful for everyone in #RWE. More info👇
CAUSALab@CAUSALab

It was great to welcome the @TARGETGuideline team to @HarvardChanSPH to reach consensus on items for a #ReportingGuideline for target trial emulation. We look forward to the guideline being piloted and released in the coming year Sign up to contribute via redcap.link/target-piloting
