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

Parathyroid carcinoma is a rare form of cancer. We describe a 45-year-old man diagnosed with parathyroid carcinoma long after initial surgery. At age 24, the patient had elevated serum calcium and intact parathyroid hormone (PTH). Ultrasonography revealed a left lower parathyroid tumor, which led to the diagnosis of primary hyperparathyroidism. Parathyroidectomy was performed, and the pathological diagnosis was parathyroid adenoma. At age 32, hypercalcemia and elevated intact PTH recurred, and computed tomography revealed a right lung tumor with focal uptake on
