Chronobiotic and cytoprotective activity of melatonin in the cardiovascular system. Doses matter.
Review in Npj biological timing and sleep, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A circadian disruption, manifested by disturbed sleep and low-grade inflammation, is commonly seen in cardiovascular diseases (CVDs). The decline in plasma melatonin, which is a conserved phylogenetic molecule across all known aerobic creatures, is also a common feature in CVDs. The daily evening pineal melatonin surge synchronizes both the central pacemaker located in the hypothalamic suprachiasmatic nuclei and myriads of cellular clocks in the periphery ("chronobiotic effect"). Melatonin also has cytoprotective properties, acting primarily not only as an antioxidant by buffering free radicals but also by regulating inflammation. In CVDs, exogenous melatonin administration decreases nocturnal hypertension, improves systolic and diastolic blood pressure, reduces the pulsatility index in the internal carotid artery, decreases platelet aggregation, and reduces serum catecholamine levels. Melatonin evokes an increase in parasympathetic activity in the heart. Allometric calculations based on animal research show that melatonin's cytoprotective benefits in CVDs may require high doses to be fully manifested (in the 100-200 mg/day range). If melatonin is expected to improve health in CVDs, the low doses currently used in clinical trials (i.e., 2-10 mg) are presumably insufficient.
