Abstract

fetched live from OpenAlex

Background Multiple prior treatment failures are associated with reduced rates of remission to subsequent antidepressant treatment, including rTMS. The degree of treatment resistance that is especially predictive of inferior outcome is uncertain. Intermittent theta burst stimulation (iTBS) is a newer form of rTMS where less is known regarding clinical predictors of remission. The THREE-D study demonstrated that iTBS is non-inferior to 10 Hz rTMS for the treatment of depression. Objective Determine if the number and type of prior pharmacotherapy trials affect the rate of remission with two types of rTMS. Method Compare remission rates based on prior pharmacotherapy using data from the THREE-D trial (NCT01887782). Results No differences in remission rates were noted between the three levels of treatment resistance, however, participants with 3 compared to <3 treatment failures had lower rates of remission: 17.3% versus 29.4% (χ 2 4.87; df = 1; p = 0.03). Conclusions Three or more treatment failures may be associated with lower remission rates with rTMS.

Not 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.
