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

purposeNonfunctional parathyroid carcinoma (PTC) is one of the rarest malignant diseases and only nine cases have been reported during the last 23 years. We present a case of nonfunctioning PTC and review the literature in an effort to provide a better understanding of this rare disorder.

methodsOne patient with nonfunctioning PTC was presented, detailing the clinical features, histologic findings, diagnosis, and treatment. Together with data from the other nine cases reported last 23 years, the related literature is also reviewed.

resultsThe presented case was a 47-year-old man with a 2-month history of an enlarging painless cervical mass followed by a 2-week history of hoarseness. Clinical and laboratory evaluations failed to reveal evidence of hyperparathyroidism. Pathological analysis of the resected tumor disclosed findings consistent with PTC. The nonsecretory state of the tumor was further supported by immunoreactivity for parathyroid hormone in tissue, and normal serum levels of this peptide and calcium preoperatively and postoperatively.

conclusionMost nonfunctional PTC is detected late due to a paucity of symptoms, of which a palpable neck mass is the most common. Patients with nonfunctioning PTC appear to have a poorer prognosis than do those with functioning parathyroid cancers.
