Mechanisms¶
- Baseline Characteristics Table
- A close cousin is the Table 1 fallacy: appending significance tests to each baseline row in a randomized trial, which is logically incoherent because any difference there arose by the chance the randomization is known to produce, so the test answers a question no one is asking.
This sourceFinds significance tests of baseline homogeneity in randomized trials philosophically unsound and of no practical value.

- Randomization Integrity Audit
- A realized allocation will differ from the intended split by ordinary sampling variation
This sourceExplains why baseline differences can arise under proper randomization.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
