Clinical Implications of Lymph Node Thyroglobulin in Papillary Thyroid Carcinoma Metastases: Independent from Thyroglobulin Antibody Interference.

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
Papillary thyroid carcinoma (PTC) frequently involves cervical lymph node (LN) metastases and is a major determinant of prognosis and recurrence. However, cytology alone has limitations. Fine-needle aspiration thyroglobulin (FNA-Tg) has emerged as a promising diagnostic marker, although its cutoff value remains controversial, particularly in patients with thyroglobulin antibodies (TgAbs). We retrospectively analyzed 63 LNs of 60 patients with PTC at a single medical center. Patients underwent FNA-Tg measurements and concurrent cytological evaluation. Diagnostic performance metrics, including sensitivity, specificity, positive and negative predictive value, and overall accuracy, were evaluated; the cutoff value was determined; and the potential influence of factors such as TgAb on FNA-Tg levels was investigated. A cutoff value of 4.23 ng/mL for FNA-Tg achieved 100% sensitivity and 90.2% specificity, with an overall accuracy of 93.6%. TgAb positivity did not significantly affect the diagnostic performance in patients with FNA-Tg. FNA-Tg might be useful for detecting local LN recurrence and providing valuable diagnostic insights, particularly in patients with residual thyroid tissue or positive TgAbs.
