Calvarial Pyramid Presenting as Occult Metastasis of Follicular Thyroid Carcinoma.
Article in Journal of cytology. 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
Follicular thyroid carcinoma (FTC) is a malignant follicular cell-derived neoplasm with prominent hematogenous spread. Metastases may be the presenting symptom; however, scalp metastasis is uncommon. A 66-year-old woman presented with progressive scalp swelling since 4 years accompanied by bilateral lower limb weakness and incontinence. On examination, there was a large 10-cm parietal scalp mass. Fine-needle aspiration smears prepared from the pyramidal scalp swelling showed microfollicular arrangement of uniform tumor cells. Diffuse positivity for pancytokeratin, PAX 8, and thyroglobulin on cell block immunocytochemistry confirmed the diagnosis of metastatic FTC. fluorodeoxyglucose avid lesions in the right lobe of the thyroid and multiple skeletal lesions were seen on positron emission tomography-computed tomography done subsequently. Despite I-131 treatment, she succumbed to death 6 months post-diagnosis. The index case highlights the utility of fine-needle aspiration cytology and the application of immunocytochemistry on cell blocks changing the norms for diagnosing carcinomas with an unknown primary.
