Unusual presentation of left atrial myxoma in a child mimicking acute poststreptococcal glomerulonephritis.
Article in Annals of pediatric cardiology. 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
Cardiac myxomas are rare in children and can mimic other conditions. We report a 14-year-old boy initially diagnosed with acute poststreptococcal glomerulonephritis based on hematuria, mild proteinuria, and elevated anti-streptolysin-O titers. However, worsening dyspnea, edema, and signs of heart failure prompted further evaluation. Echocardiography revealed a large left atrial mass with impaired biventricular function and tricuspid regurgitation. Surgical excision confirmed a myxoma. The patient's renal and systemic symptoms were attributed to low cardiac output and venous congestion, not true glomerulonephritis. This case highlights the need to consider cardiac causes in pediatric patients with persistent nephritic-like features.
