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

Pulmonary artery intimal sarcoma (PAIS) is a rare, aggressive mesenchymal tumor arising in the large vessels of pulmonary circulation with nonspecific clinical features that can resemble common pulmonary conditions such as tuberculosis (TB), particularly in TB-endemic regions. We report a 51-year-old woman with prior TB exposure who presented with a two-month history of productive cough, dyspnea, low-grade fever, and weight loss. Chest radiography showed multifocal patchy opacities and right pleural effusion, leading to empirical treatment for smear-negative TB. Her condition deteriorated, and contrast-enhanced CT revealed a lobulated mass occupying the pulmonary arteries with pulmonary and pleural metastases. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) with histopathological analysis confirmed PAIS. Despite palliative management, including bronchial artery embolization for hemoptysis, the disease progressed rapidly, and the patient died three months after diagnosis. This case highlights the diagnostic challenges of PAIS and the importance of maintaining a broad differential diagnosis. Early recognition is essential due to the tumor's aggressive progression and poor prognosis.
