Primary Pericardial Angiosarcoma Demonstrating Initial Response Followed by Progression on First-Line Chemotherapy: A Case Report.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Primary pericardial angiosarcoma is an exceedingly rare and highly aggressive malignancy arising from pericardial endothelial cells, with a reported median survival of approximately 7 months. Owing to its non-specific clinical presentation, diagnosis is frequently delayed, particularly in tuberculosis-endemic regions, where symptoms may be attributed to tuberculous pericarditis. We report the case of a 25-year-old Nepalese male who presented with a six-month history of progressively worsening dyspnea (MMRC grade 1 to 4) and an ECOG performance status of 3. Initial evaluation revealed a large pericardial effusion and a right atrial mass measuring 4.5 × 3.7 × 3.2 cm on MDCT. Based on trace
