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

Type A thymoma is associated with an excellent prognosis, and distant metastasis is uncommon. Optimal management for metastatic type A thymoma has not been well documented. We report a case of conventional type A thymoma with synchronous solitary pulmonary metastasis treated with simultaneous resection. An 81-year-old woman was incidentally found to have both a 2.0 cm anterior mediastinal nodule and a 0.9 cm pulmonary nodule in the left lower lobe. Both lesions were resected via video-assisted thoracoscopic surgery. Histopathology and immunohistochemistry revealed identical features in both tumours, confirming type A thymoma with solitary pulmonary metastasis (pT1aN0M1b, stage IVb). No histopathological features of atypical type A thymoma were present. The patient remains recurrence-free 1 year after surgery without adjuvant therapy. This case suggests that pulmonary metastasis can occur even in small, low-grade type A thymoma and that simultaneous resection for diagnostic and therapeutic purposes may be considered to achieve favourable outcomes.
