Relationship between motor function and ultrasonic vocalizations induced by maternal separation in rat pups.

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
When rat pups are isolated from their mothers, they emit ultrasonic vocalizations (USVs). Although previous studies have reported that USVs are related to anxiety, others have reported that they are related to simple, nonemotional factors, such as physiological reactions to coldness. In this study, we examined the influence of three maternal separations on rat pups. The number of USVs during 5 min of USV test under maternal separation, latency in the righting reflex as motor function, and body temperature were recorded twice (the first and second tests) before and after the pups were put in various environments for 10 min. The environments were no maternal separation (Control: CON), maternal separation with littermates (LMS), and single maternal separation with a heater (SMS). In the second test, the SMS pups had fewer USVs, a lower body temperature, and a more rapid righting reflex than the CON and LMS pups. In addition, there was no strong correlation between USVs and righting reflex. As a result, pups undergoing 10 min of SMS while being kept warm by the heater showed rapid righting reflex. Thus, by a single maternal separation, the number of USVs decreased but the decrease was unrelated to decrease in motor function.
