1 · What the graph read from it

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.

2 · The registry

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

Occult thyroid carcinoma (OTC) involves cervical lymph node metastases without primary papillary thyroid carcinoma (PTC). A 57-year-old man presented with a left neck mass. Ultrasonography (US) revealed a mass in the left cervical node (inferior internal jugular node, Level IV). Positron emission tomography/computed tomography (PET/CT) and fine needle aspiration biopsy indicated suspected PTC metastasis. The serum thyroglobulin (Tg) level was elevated. Total thyroidectomy and bilateral central neck and left cervical dissection revealed no thyroid carcinoma, while the left cervical node showed ground glass nuclei and proliferation. Our diagnosis was PTC with no primary origin, pT0N1bM0 Stage II. Due to a low risk of recurrence, we initiated thyroid-stimulating hormone (TSH) suppression therapy. Tg levels remained low 4 years postoperatively with no signs of recurrence. The optimal management of OTC cases remains unclear and blood tests (Tg levels), risk of recurrence, and patient characteristics must be considered.
