Sibling number and early interactions shape social competence for life.

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
The social environment experienced during development plays a crucial role in shaping social competence-the ability to respond appropriately to social challenges. Sibling number and the social interactions between them are key components of the early lives in many animals. While these components are well known to influence social development in humans, their role in nonhuman animals remains unclear. Here, we show that both the number of siblings and opportunities for social interaction are essential for developing social competence in the highly social cichlid
