Abstract
In previous chapters, the different steps of a de-implementation process were described. In this chapter, we will provide examples of studies that include each phase of the framework. Chapters 2 and 3 elaborated on the reasons for overuse and the determinants on the different levels. We described in detail why it is so hard to change behaviour and the specific determinants that are more relevant for de-implementation compared to implementation. In Chapter 4, the phases of the de-implementation framework have been introduced, and the following chapters described these phases in more detail. This chapter puts the framework together so that you can see how the project moved through the different phases. The studies in this chapter provide a variety of low-value care to target as well as healthcare professionals in different countries as well as different types of study design and evaluation.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
