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

Partially calcified organized thrombi of the right atrium are rare and may mimic cardiac tumors, making preoperative diagnosis challenging. A 60-year-old man was found to have a partially calcified right atrial mass during evaluation for atrial flutter. Despite anticoagulation therapy, the lesion persisted and a neoplastic process could not be excluded. Therefore, surgical resection was performed through a right mini-thoracotomy approach. Histopathological examination revealed a chronic organized thrombus with focal calcification and hemosiderin-laden macrophages. The postoperative course was uneventful, and no recurrence was observed during 2 years of follow-up. This case highlights the diagnostic challenge of partially calcified right atrial masses and suggests that a minimally invasive approach may provide a useful option for both diagnosis and treatment in selected patients.
