Noradrenergic pathway from the locus coeruleus to heart is implicated in modulating SUDEP.
Article in iScience, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Sudden unexpected death in epilepsy (SUDEP) is the leading cause of death among epilepsy patients. However, the underlying mechanism remains elusive. Seizure-induced respiratory arrest (S-IRA) is recognized as a main cause of SUDEP, but the contribution of other factors such as cardiac arrhythmias cannot be excluded. Here, we found that both the locus coeruleus (LC) and peripheral noradrenergic neurotransmission were involved in S-IRA and the protective effect of atomoxetine in reducing the occurrence of S-IRA and SUDEP could be reversed by esmolol hydrochloride. Moreover, we investigated the connection between the LC and heart implicated in the modulation of SUDEP by fiber photometry. These data suggested that noradrenergic neurons in the LC might regulate the occurrence of SUDEP through β1-adrenergic receptors on cardiomyocytes. Overall, our findings indicate the involvement of the brain-heart axis in modulating S-IRA and SUDEP and, therefore, will open a new perspective on decoding SUDEP.
