Chronic high-dose testosterone disrupts social cognition and enhances social dominance in male long-Evans rats.

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
While increased aggression is the most consistent behavioral effect of anabolic androgenic steroid (AAS) abuse, its cause remains unclear. AAS may promote aggression by disrupting social behaviors which maintain dominance hierarchies. To model AAS abuse, we treated male rats with chronic high-dose testosterone and tested social recognition, social learning, and competitive and aggressive dominance. Rats received daily injections s.c. of testosterone (7.5 mg/kg) or vehicle (n = 8/group). We tested social recognition by measuring investigation of a novel or familiar stimulus animal, social learning with the social transmission of food preference (STFP) test, aggressive dominance with the tube test, and competitive dominance with a food competition task. For social recognition, testosterone-treated rats did not prefer the novel stimulus rat (72.8 ± 9.3 s) over the familiar rat (68.8 ± 8.0 s, N.S.) rat. In the STFP test, testosterone-treated rats did not show a significant preference for the demonstrated flavor (59.9 ± 9.4 %, N.S.) compared with controls (70.1 ± 5.4 %, p < 0.05). In the tube test, testosterone did not increase the number of rounds won. However, when the testosterone-treated rat won, they were more likely to be lighter than their vehicle-treated opponent, χ
