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
In both humans and rodents, maternal care is disturbed by exposure to environmental adversity, including low resource conditions (i.e., poverty, scarcity). Maternal adversity is associated with compromised quality of mother-infant attachment and increased adverse caregiving patterns such as abuse, maltreatment and/or neglect, which disrupt behavioral development in the female offspring. Importantly, maternal behavior is thought to be an intergenerational behavior, meaning that the quality of maternal care a female experiences during early life is thought to influence the quality of care she will display towards her own offspring when she becomes a mother. Here, we tested this idea by employing a rodent model of postpartum environmental adversity based on creating an impoverished nesting environment during postpartum days (PD) 2-9, which disrupts mother-infant interactions and is thought to upregulate hypothalamic-pituitary-adrenal (HPA)-axis function in the pups. We examined the impact of this form of early life adversity on pup stress hormone (i.e., corticosterone- CORT) levels by collecting trunk blood and later life maternal behavior by conducting maternal behavior observations and maternal motivation tests (e.g., T-Maze, pup retrieval, pup-associated conditioned place preference) in the first filial (F1) generation. We report no impact of early life scarcity-adversity/adverse caregiving on pup CORT levels or later life naturalistic or motivated maternal behaviors. In sum, we show that female rat pups who experienced adverse caregiving during early life showed resilience towards developing negative caregiving patterns, as they did not perpetuate the same aberrant maternal behavior that they received from their mothers.
