Connexin 43 dephosphorylation contributes to arrhythmias and cardiomyocyte apoptosis in ischemia/reperfusion hearts.
Article in Basic research in cardiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 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
Connexin 43 (Cx43)-associated gap junctions form electrical and mechanical conduits between adjacent ventricular cardiomyocytes, ensuring coordinate electrical excitation and synchronic contraction for each heartbeat. Cx43 dephosphorylation is a characteristic of ischemia, arrhythmia, and a failing and aging myocardium, but the exact phosphosite(s) triggering myocardial apoptosis and electrical disturbance and its underlying mechanisms are unclear. We previously found that Cx43-serine 282 phosphorylation (pS282) can regulate cardiomyocyte survival and electrical stability. Here, we investigated the hypothesis that S282 dephosphorylation occurs in and contributes to ischemia/reperfusion (I/R)-induced cardiac injury. We found enhanced Cx43-pS262 and Cx43-pS368 but decreased Cx43-pS282 in rat hearts subjected to I/R (30 min/2 h). I/R rats had ventricular arrhythmias and myocardial apoptosis with activation of the p38 mitogen-activated protein kinase (p38)/factor-associated suicide (Fas)/Fas-associating protein with a novel death domain (FADD) pathway. Similarly, S282 dephosphorylation, abnormal Ca
