Urocortin 2 Gene Transfer Improves Heart Function in Aged Mice.

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
Prevalence of left ventricular (LV) systolic and diastolic dysfunction increases with aging. We previously reported that urocortin 2 (Ucn2) gene transfer increases heart function in mice with heart failure with reduced ejection fraction. Here, we test the hypotheses that (1) Ucn2 gene transfer will increase LV function in aged mice and that (2) Ucn2 gene transfer given in early life will prevent age-related LV dysfunction. Nineteen-month-old (treatment study) and 3-month-old (prevention study) mice received Ucn2 gene transfer or saline. LV function was examined 3-4 months (treatment study) or 20 months (prevention study) after Ucn2 gene transfer or saline injection. In both the treatment and prevention strategies, Ucn2 gene transfer increased ejection fraction, reduced LV volume, increased LV peak -dP/dt and peak +dP/dt, and reduced global longitudinal strain. Ucn2 gene transfer-in both treatment and prevention strategies-was associated with higher levels of LV SERCA2a protein, reduced phosphorylation of LV CaMKIIa, and reduced LV α-skeletal actin mRNA expression (reflecting reduced cardiac stress). In conclusion, Ucn2 gene transfer restores normal cardiac function in mice with age-related LV dysfunction and prevents development of LV dysfunction.
