Calcium in atrial fibrillation - pulling the trigger or not?
Article in The Journal of clinical investigation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Atrial fibrillation (AF) is the most common sustained arrhythmia disease. Current drug- and surgical-based therapies are ineffective in about 40% to 50% of AF patients; therefore, there is a great need to better understand the underlying mechanisms of this disease and identify potential therapeutic targets. In this issue of the JCI, Greiser and coworkers discovered that atrial remodeling in response to sustained tachycardia silences Ca2+ signaling in isolated rabbit and human atrial myocytes. This Ca2+ release silencing was attributable to a failure of subcellular propagated Ca2+ release due to an increased cytosolic buffering strength. The results from this study challenge the current paradigm that Ca2+ release instability underlies AF. Instead, Ca2+ silencing could be protective against the massive cellular Ca2+ loading that occurs during chronic AF.
