1 · What the graph read from it

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.

2 · The registry

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

Exposure to environmental enrichment has beneficial effects on learning and memory, diverse neurobiological effects, and promotes recovery of function after brain injury. The effect of enrichment is produced by a combination of increased social interaction, physical activity, spatial complexity, and novelty. Procedures in the literature have, however, been idiosyncratic with poor consistency in the manner or extent to which protocols provide consistent enrichment. We provide an environmental enrichment protocol that can be easily replicated with minor details determined locally so that animals across cohorts and cages all experience a comparable level of enrichment. Procedures are outlined to generate and use a daily pool of suitably varied objects using a standardized format, with objects systematically varied up to a 40-day continuous period. Together with using a large group of rats in a suitably-sized cage, and regular shifting of the position of food and water and cage location, these procedures have produced robust effects in different laboratories and rat strain, thereby improving comparisons within and across laboratories. Non-enriched comparisons can vary, but typically would include grouped animals in standard laboratory housing without objects and with stable food and water locations. Enrichment is a safe non-pharamacological tool to examine behavioral and neurobiological processes in animal models of the lifespan, brain dysfunction and injury.
