Today is detection bias. Which is so simple even Trump understands it!

It’s September which means RFK Jr will soon be releasing his promised report on the ‘causes’ of autism. Until then, we're learning about important biases.

Today's post is all about how a badly designed study can make it look like people live forever.

And how, if you only apply this to one group, you can essentially guarantee any study result you want. 😬

When using observational data for #causalinference, the choice isn’t between emulating or not emulating a #TargetTrial, but between reporting or not reporting the target trial that we are emulating.

For those who prefer to be explicit about what they do, we have developed the TARGET Statement 👇
