2023, and I am still evaluating study protocols in which researchers write "if results are positive, they will be published".😳

Great new read from @stephensenn for any trialist, observationalist or casualist with an interest in analyzing data that are nested (or clustered, multilevel,...)

No matter what you were taught,
don't bother to test for proportional hazards
in survival analyses.
Hazards are never proportional because hazard ratios vary over the follow-up if treatment has an effect on survival.
@mats_julius and I explain it here:

From its inception, EBM has had its critics. In 2008 we were asked to engage in a debate about whether EBM has a sound scientific basis. The paper we wrote for the debate presents one of the nicest explanations of the role of EBM and what it offers. doi.org/10.1378/chest.08-006…

Because what patients care about is absolute and not relative effects, it is crucial that systematic reviews provide absolute as well as relative effect estimates. Sadly, they very often don’t. doi.org/10.1016/j.jclinepi.2…

Helpful and insightful explanation of how predictive values change when prevalence changes.
But beware - it is not certain that sensitivity and specificity remain unchanged.
In theory they do, but in reality different prevalence may correspond with a different patient spectrum/

We wrote a comment on interpreting the AUC, including a literature search of qualitative labels (w/ Anne de Hond and @ESteyerberg):

I’ve spoken recently about how EBM teaching should move away from risk of bias/methods to understanding overall quality of evidence & results. Latest a 10 minute exposition for a meeting celebrating the 25th anniversary of the Iberoamerican Cochrane Center youtu.be/RfLlPChUlqU

Have we opened a ‘Pandora’s Box’ of Systematic Review types?
We discuss this (and more) in our recent @BMJ_EBM paper 👇
