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

introductionPrimary hepatic neuroendocrine tumors (PHNETs) are extremely rare, having less than 200 cases reported in the literature. PRESENTATION OF CASE: A 51-year-old woman presenting with mild intensity sharp pain in the upper abdomen that started 4 years ago. Preoperative Magnetic Resonance Imaging (MRI) suggested hepatocellular adenoma. Surgical exploration found a tumor occupying the whole segment IV of the liver, therefore a left hepatectomy was performed. Pathology and immunohistochemistry indicated to be a low-grade neuroendocrine tumor of the liver. The patient is enjoying a good quality of life, free of disease, presenting no signs of recurrence nor metastases 12 months after the procedure.

conclusionThe clinical presentation of PHNETs is non-specific and its radiologic features are intensely diversified, frequently leading to misdiagnosis of other hepatic neoplasms.
