Contrast-enhanced ultrasound combined with diagnostic nerve block for differentiating cervical sympathetic ganglion from metastatic lymph node: a case report.
Article in Journal of ultrasound, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Differentiating cervical sympathetic ganglion (CSG) from metastatic lymph nodes in the central neck compartment remains a diagnostic challenge, particularly in patients with thyroid carcinoma. Conventional imaging modalities, including contrast-enhanced computed tomography (CT) and ultrasound, may yield indeterminate findings due to overlapping morphological characteristics. We present a case with papillary thyroid microcarcinoma that was referred for thermal ablation. Preoperative CT suggested a suspicious level VI lymph node. Contrast-enhanced ultrasound (CEUS) combined with diagnostic ultrasound-guided nerve block for differentiating cervical sympathetic ganglion from metastatic lymph node was performed. The appearance of Horner syndrome after nerve block indicates that this lesion is a sympathetic ganglion.
