Hormonal correlation with abnormal thyroid function and their auxiliary diagnostic value in breast cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate the association between thyroid hormone levels and pathological characteristics in patients with breast cancer.
methodsA retrospective analysis was conducted on 120 breast cancer patients who received treatment at the First Affiliated Hospital of Xi'an Jiaotong University between January 2020 and December 2023. A total of 100 healthy individuals undergoing routine physical examinations were enrolled as the control group. Serum levels of free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH), thyroglobulin antibody (TG-Ab), and Thyroid peroxidase antibody (TPO-Ab) were measured and compared between the two groups. The diagnostic performance of thyroid hormones for breast cancer was evaluated using receiver operating characteristic (ROC) curve analysis, and correlations between thyroid hormone levels and pathological features of breast cancer were further analyzed.
resultsNo significant differences were observed in serum FT3, TSH, T3, or T4 levels between the two groups (P = 0.446, 0.594, 0.405 and 0.781, respectively). Compared with healthy controls, patients with breast cancer were observed to have significantly higher FT4 levels and substantially higher TPO-Ab levels, despite both parameters remaining within their normal reference ranges (all P < 0.001). ROC analysis demonstrated that the areas under the curve (AUCs) of FT4 and TPO-Ab for predicting breast cancer were 0.701 and 0.805, respectively. Furthermore, FT4 levels were significantly associated with tumor size, clinical stage, and lymph node metastasis (all P < 0.001). TPO-Ab levels were significantly correlated with tumor size, clinical stage, lymph node metastasis, and the expression of estrogen receptor (ER) and progesterone receptor (PR) (P = 0.006, 0.015, 0.046, 0.048 and 0.017, respectively). Follow-up analysis further revealed that clinical stage, lymph node metastasis, postoperative radiotherapy and chemotherapy, ER and PR expression, as well as FT4 and TPO-Ab levels, were independent factors influencing breast cancer recurrence.
conclusionSerum FT4 and TPO-Ab levels are closely associated with the occurrence, progression, and specific pathological features of breast cancer, demonstrating favorable diagnostic and predictive value. Moreover, they may serve as important potential biomarkers for evaluating the risk of recurrence in patients with breast cancer.
