Sexually Dimorphic Effect of Environmental Enrichment and Weaning on Stress in Piglets.

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
Most intensive swine production systems use invasive practices that increase stress and compromise animal welfare. Apparently, the way in which animals respond to stress is sexually dimorphic. To cope with stress and improve the life of animals, environmental enrichment (EE) is used. The objective of the study was to evaluate how EE and weaning affect the behavior and cortisol levels of barrows and female piglets. Forty piglets were divided into two groups: (1) WEE: piglets that received EE from birth until 21 days of age and whose mothers received EE from week six of gestation until farrowing; (2) NEE: piglets for whom neither them nor their mothers received EE. Cortisol fecal metabolites and frequency, latency and duration of behaviors associated with stress were evaluated and compared before and after weaning. Before weaning, WEE barrows showed less inactive and ingestion behaviors and shorter duration of aggression (
