Investigation of the Mozart sonata effect on contextual memory extinction.

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
objectiveThis study aimed to analyze the influence of Mozart's Sonata K.448 on contextual memory extinction in male mice.
methodsMale mice were divided into three groups (G1-Mozart, G2-Ambience, G3-Control). Throughout the project, only the first group was exposed to the sonata at the intrauterine stage. Only Groups 1 and 2 underwent aversive training; subsequently, all groups participated in extinction and recall tests.
resultsOn the first day of extinction, G1's freezing time was longer than G2's and G3's, whilst on the second day it was only longer than G3's. Finally, on the fifth day, G1's freezing time was shorter than that of G2. During the second and third days of extinction, G1's freezing time decreased more than G3's, whereas during the fourth and fifth day, G1 upheld its freezing time, whereas G2's extended. During recall, G1 had a longer freezing time than G3. All results were statistically significant (p≤0.05).
conclusionBased on the results, we concluded that male mice exposed to Mozart's Sonata K.448 showed increased freezing time, suggesting an impact of the music on memory formation. However, they exhibited a linear extinction memory process. This progressive decrease in freezing behavior was not observed in the ambient and Control Groups.
backgroundThis study analyzed the influence of Mozart's Sonata K.448 on contextual memory extinction in male mice. The mice were divided into three groups, with only G1 mice exposed to the sonata. G1 initially showed longer freezing times but exhibited a linear extinction process, unlike G2 and G3. These results suggest that the sonata affected memory formation while aiding progressive extinction.
background■ In this study, mice were exposed to music at the intrauterine stage.
background■ Music exposure before aversive memory formation enhances neuroplasticity, aiding in extinction.
background■ The recall test showed that music exposure had sustained beneficial long-term effects.
