Is thyroglobulin detection in fine-needle aspirates useful for the diagnosis of central neck metastatic papillary thyroid 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
Objective: The central neck lymph node (LN) status is important for the treatment strategy of papillary thyroid cancer (PTC), while the diagnosis is difficult. This study aims to evaluate the diagnostic value of fine-needle aspiration (FNA) and its washout thyroglobulin (FNA-Tg) detection in central neck LN metastasis. Methods: Central neck LNs with FNA cytology (FNA-C) and FNA-Tg measurements from a tertiary hospital were included. Tg levels were correlated with histopathological or follow-up results. The diagnostic performance of FNA-C, FNA-Tg, and combining FNA-C and FNA-Tg for detecting LN metastasis was assessed. Results: A total of 132 LNs in the central neck from 129 patients were studied. The median FNA-Tg concentration of 74 metastatic LNs was 552.5 ng/mL, whereas, in 58 benign LNs, the median Tg concentration was 0.1 ng/mL (P < 0.001). Receiver operating characteristic analysis (area under the curve, 0.861) was used, and a cutoff value of 14.6 ng/mL was obtained. There was no significant increase in the diagnostic accuracy when FNA-Tg was used or combined with FNA-C, compared with FNA-C alone. The size, location of LNs, the presence of the ipsilateral thyroid gland, and Hashimoto's thyroiditis did not affect the incidence of misdiagnosis. Conclusions: FNA-C is the gold standard for evaluating central neck metastasis in PTC patients. Measurement of Tg levels in FNA washout does not improve the diagnostic accuracy any further.
