Abstract
Background: Repetitive transcranial magnetic stimulation (rTMS) is cleared by the Food and Drug Administration for major depression, and recently received breakthrough status for bipolar depression (BDep). However, evidence on its efficacy and safety and optimal protocols for BDep remains limited. We conducted a systematic review to synthesize available data on rTMS for BDep. Methods: We systematically searched 4 literature databases for studies published between 1995 and 2025 treating participants with acute BDep (1097 articles). The primary outcome for the meta-analysis was change in mean depression severity scores from baseline. Determinants of treatment response were assessed using meta-regression and subgroup meta-analyses. Results: = 1.4), with rates of response (46.81%) and remission (28.25%) similar to those described for MDD and preserved in subanalyses for high-frequency protocols, including intermittent theta burst stimulation (iTBS) delivered to the left dorsolateral prefrontal cortex (DLPFC) and low-frequency protocols delivered to the right DLPFC. Higher baseline illness severity and more treatment sessions were predictors of greater antidepressant effect. Conclusions: TMS is efficacious and safe in BDep, with response and remission rates on par with rates for unipolar depression. High- and low-frequency protocols on the left and right DLPFC, respectively, are robustly associated with positive outcomes, with left DLPFC iTBS showing noninferiority to more widely used high-frequency rTMS protocols.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
