Sacral Metastasis in Follicular Thyroid Carcinoma: Cytology Pitfalls and Serum Thyroglobulin Utility.

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
Sacral bone metastasis from primary follicular thyroid carcinoma (FTC) is rare. Most reported cases include factors indicative of thyroid origin, such as a history of treated thyroid cancer or newly identified thyroid nodules with malignant cytology. We herein report a 57-year-old woman with a metastatic sacral lesion of thyroid origin, initially misdiagnosed due to a false-negative fine-needle aspiration (FNA) cytology result of a thyroid nodule. The diagnosis was suspected based on an abnormally elevated serum thyroglobulin (sTg) level and confirmed through repeat core biopsy with thyroid-specific immunohistochemistry. This case highlights the limitations of FNA cytology in large thyroid nodules and underscores the potential role of sTg in diagnosing metastatic FTC in certain clinical scenarios. Thyroid carcinoma should be considered in the differential diagnosis of sacral metastases when the primary tumor is unknown.
