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

introductionSolitary fibrous tumors of the pleura (SFTPs) are rare mesenchymal neoplasms that are usually benign but may occasionally recur or undergo malignant transformation. Tumor size is an important prognostic factor; lesions larger than 10 cm are associated with recurrence and poor outcomes, and tumor size ≥15 cm is considered as a risk factor in prognostic models. Histologically, benign SFTPs of ≥15 cm in size are extremely uncommon. CASE PRESENTATION: A 48-year-old male presented with exertional dyspnea and chest tightness. Chest CT revealed a giant mediastinal mass measuring 138 × 91 × 129 mm. The encapsulated tumor originated from the pleura and was completely resected via a thoracotomy. Histological examination revealed spindle cells with hyalinization and calcification, without necrosis or mitotic figures. Immunohistochemical staining was positive for CD34 and STAT6, confirming a diagnosis of SFTP. The resected specimen measured 185 × 80 × 145 mm, with a low Ki-67 labeling index of 3%, and was classified as low risk according to the 4-variable Demicco risk stratification model.

conclusionsWe report a rare case of a histologically benign but giant SFTP exceeding 15 cm in diameter. Although classified as low risk, large tumor size itself may reflect biological aggressiveness and be associated with recurrence or malignant transformation. Therefore, careful long-term follow-up is required.
