The mean age of the participants was 30.1 ± 9.0 years, ranging from 18 to 53 years, with 29.6% being male and 70.4% female. After 8 weeks of treatment, significant reductions were observed in PHQ-15 scores (− 5.8 ± 4.4, P < 0.001) and SSS-CN scores (− 12.8 ± 10.3, P < 0.001), indicating improvement in somatic symptoms. Secondary outcomes also showed significant improvements in depressive symptoms (HAMD-17: − 15.3 ± 7.4, P < 0.001), pain intensity (VAS: − 1.97 ± 2.44, P < 0.001), fatigue (MFI-20: − 12.8 ± 14.1, P < 0.001), and functional disability (SDS: − 8.3 ± 6.5, P < 0.001). The occurrence of adverse events was 52.5%, with no serious adverse events reported.Conclusion: Toludesvenlafaxine hydrochloride significantly improved somatic symptoms in patients with MDD and somatic symptoms, with a favorable safety profile, supporting its use as an effective treatment option.Clinicaltrials.gov Identifier: NCT05849272.Keywords: major depressive disorder, somatic symptoms, toludesvenlafaxine, clinical trial, safety, efficacy

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.
