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

Background: Saw-tooth cardiomyopathy is a rare condition characterized by left ventricular (LV) dysplasia, defined by multiple myocardial crypts resembling a 'saw-tooth' pattern on imaging examinations. Case Summary: We present a case involving a 10-day-old neonate who was diagnosed with saw-tooth cardiomyopathy, a diagnosis substantiated by echocardiography, computed tomography (CT), and cardiac magnetic resonance imaging (CMR). The patient demonstrated arrhythmia characterized by premature atrial contractions and had a suspected cardiomyopathy identified during the foetal period. Discussion: The diagnosis of this condition is solely based on morphological features and may be misdiagnosed as LV non-compaction. Imaging modalities, including echocardiography, CT, and CMR are valuable diagnostic tools. Owing to its rarity and unclear pathogenesis, the prognosis of saw-tooth cardiomyopathy remains uncertain, necessitating long-term, potentially lifelong follow-up.
