What is a fake measurement tool and how are they used in RCT

Here is the new SOFA 2.0.

Recall SOFA 1.0 (delta 2 SOFA points) which was guessed in 1996 is still the entry criteria for sepsis cause agnostic RCTs (CARs) in critical care. It is also used as a primary or secondary outcome either as a score or a pre and end trial SOFA difference. It is also used as an independent variable.

Now there is a new SOFA 2.0, the product of Delphi 2.0, that bastion of scientific rigor. SOFA as a RCT gate (S=1) is of course a collider and this use only makes sense to those who think the task force can guess each new generation’s disease and cause agnostic gate (S=1) to harmonize the worlds sepsis for RCTs

If you want to understand all of this come over to the thread about the “cause-agnostic RCT” (CAR). That is what SOFA 2.” Is for.

Cause-Agnostic RCT (CAR)

Over on X there is a debate relevant causal inference vs RCT design. But what is an RCT? Since Bradford Hill’s landmark study we have seen the RCT morph into two species. So can we no longer speak of or debate RCTs as if they comprise a unified entity… a thing. There are CIRs (causal-integrity RCTs) for example the original Bradford Hill causal design, and CARs (causa-agnostic RCTs). a CIR conditions on a cause AND a covariate vector. a CAR conditions one or more thresholds (S=1) and …
