Bibliographic record
Abstract
Objective To investigate the effect of levothyrocine-thyroxine 4 (L-T4) replacement therapy on cognitive status in elderly patients with subclinical hypothyroidism (SCH).Methods One hundred and twenty elderly patients with SCH were selected and treated with thyroid hormone replacement therapy for 6 months.The thyroid functions and cognitive impairments were tested for all the subjects before and after the therapy.Results After 6 months of thyroid hormone replacement therapy,the level of thyrotropic hormone was significantly lower than that of before herapy((15.21 ± 1.78) mU/L vs.(3.46 ± 0.37) mU/L,t =6.417,P =0.0083));The neuropsyehological test performance in patients with hypothyroidism showed statistically significant improvements in clock drawing test,iconic memory,block design,complex graphics recall and delayed recall,trail making A,word list learningl,recall and recognize,forward and backward digital span,verbal fluency,and digital symbol from WAIS-RC ((8.74 ± 1.08) vs.(9.63 ± 1.32),(6.14 ± 1.03) vs.(8.47 ± 1.38),(30.36 ± 7.27) vs.(36.42 ±8.54),(13.71 ± 1.05) vs.(14.87 ± 1.38),(11.21 ± 1.13) vs.(13.56 ±1.34),(11.36 ± 1.27)vs.(13.06 ±1.47),(5.27 ±0.84) vs.(6.54 ±1.03),(63.13 ±12.09)vs.(54.63 ±10.07),(3.64 ± 1.07)vs.(4.91 ±1.32),(5.27 ±0.84) vs.(6.54±1.03),(8.52±1.16) vs.(9.83 ±0.96),(8.01 ± 0.83) vs.(8.94 ± 1.08),(4.04 ±0.57)vs.(5.37 ±0.75),(11.21 ± 1.03) vs.(13.43 ± 1.23),(33.46 ± 8.72) vs.(38.06 ± 9.58),t =13.907,11.027,12.093,16.374,10.361,11.536,8.794,-10.617,9.601,8.794,17.814,7.913,12.415,13.992,10.128 respectively,P =0.028,0.039,0.036,0.029,0.042,0.040,0.048,0.042,0.045,0.048,0.027,0.048,0.038,0.032,0.041 respectively).Conclusion The treatment of thyroid hormone for the edlerly patients with SCH has positive effects on theimprovement of mild cognitive impairment.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
