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

A 59-year-old woman presented with multiple mediastinal masses 6 months after post-thymectomy for type B2 thymoma. A diagnosis of small-cell carcinoma (SmCC) via a computed tomography-guided biopsy and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography revealed no primary lesions outside the anterior mediastinum. The pathologically reevaluated post-thymectomy specimen showed no neuroendocrine differentiation. SmCC is presumed to arise either from malignant transformation of the thymoma or de novo formation. She was treated with carboplatin and paclitaxel to achieve complete response. This case highlights the importance of a re-biopsy to guide appropriate treatment in cases of rapid progression during the course of thymoma.
