You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["AnatomicalEntity"].

Please return the output as a JSON object of the format: {"AnatomicalEntity": ["tumor cells", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Effects of rule-breakers on intermediary-based networks.
Individuals using rule-breaking strategy primarily affected (A) their own social position (H(2) = 213.18, p<0.0001), but also made an impact on the other aspects of the social system, affecting (B) the social position of others (H(2) = 6.79, p = 0.034) and (C) group organization (H(2) = 125.3, p<0.0001) as their frequency in a population increased. The boxes show medians, quartiles, minima and maxima. Results significantly different from a relevant uniform network with no rule-breaking behavior (p<0.05 in Dunn's multiple comparison test for comparing each group with control) are designated with *.
