Source: Retraction Watch, joined by DOI. OpenAlex records retraction as is_retracted, a boolean over a state space with at least four values, so it cannot express an expression of concern, a correction or a reinstatement; it reports them as false, which reads as “fine”.

Abstract
Despite advances in the drug treatment strategy for stable coronary heart disease (CHD), the mortality of CHD continues to rise. New or adjuvant treatments would be desirable for CHD. Xuefu Zhuyu granules are derived from the formula of traditional Chinese medicine. To determine whether Xuefu Zhuyu granules might have adjuvant effects on stable CHD, we conducted a controlled clinical trial. Patients with stable CHD were enrolled and randomly assigned to receive Xuefu Zhuyu granules or placebo for 12 weeks in addition to their standard medications for the treatment of CHD. The primary endpoints comprise the Canadian Cardiovascular Society Angina Grading Scale (CCS class), echocardiographic measures, Seattle Angina Questionnaire (SAQ), and coronary artery CT. The secondary endpoints included the parameters of nailfold capillary measurement and cutaneous blood perfusion (CBP). After 12 weeks of follow‐up, there was a great improvement of the Canadian Cardiovascular Society Angina Grading Scale (CCS class) in the Xuefu Zhuyu group compared with the placebo group ( p < 0.01). Also, a decrease was found in the percentage of patients with CCS class II in the Xuefu Zhuyu group between follow‐up at 12 weeks and baseline ( p < 0.01). We observed a significant increase in SAQ scores of physical limitation ( p < 0.01) and treatment satisfaction ( p < 0.05) in patients receiving Xuefu Zhuyu treatment at 12 weeks in comparison with those at baseline, but not in placebo treatment ( p > 0.05). Amelioration in coronary artery stenosis in the Xuefu Zhuyu group was noted ( p < 0.05). Xuefu Zhuyu granule treatment led to great improvements in cutaneous blood perfusion at follow‐up of 12 weeks compared with placebo ( p < 0.05). These findings suggest that on a background of standard medications, Xuefu Zhuyu granules have the ability to further improve the prognosis of patients with stable CHD.

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.
