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

Caseous mitral annular calcification (CMAC) is a rare morphological variant of mitral annular calcification. On echocardiography, it often appears as a mass-like echogenic lesion and may be easily misdiagnosed as an intracardiac thrombus or tumor, posing a diagnostic challenge in clinical practice. The clinical significance and potential procedural implications of CMAC in patients undergoing catheter ablation for atrial fibrillation remain poorly understood, and relevant reports are scarce. Here, we report a patient with end-stage renal disease on long-term hemodialysis who was found to have CMAC and successfully underwent radiofrequency catheter ablation for atrial fibrillation, with favorable postoperative recovery. This case highlights the critical role of multimodality imaging in the accurate diagnosis and clinical decision-making for CMAC.
