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: ["Outcome", "Participant", "Intervention"].

Please return the output as a JSON object of the format: {"Participant" : ["patients with COPD", ...], "Intervention" : ["Atenolol", ...], "Outcome" : ["blood pressure", ...]}. 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:

Penetration and accumulation of moxifloxacin in uterine tissue . OBJECTIVE To determine whether moxifloxacin penetrates the uterine tissue and accumulates at levels sufficient to eradicate the major pathogens causing pelvic inflammatory disease ( PID ) . METHOD In a prospective , multicenter , open-label , parallel-group study we determined the concentration of moxifloxacin in plasma and uterine tissue after a single , 400-mg intravenous dose of moxifloxacin . Study participants were randomized for time of tissue sampling , which was performed 1 , 2 , 4 , 7 , or 24 hours following the moxifloxacin infusion . RESULTS Of 43 participants , 40 were randomized to tissue sampling . Moxifloxacin accumulated in uterine tissue and concentrations were highest 1 hour after infusion in both plasma and tissue . Tissue to plasma ratios remained between 1.7 and 2.1 for 24 hours . Moxifloxacin was found to be safe and well tolerated . CONCLUSION Based on known minimum inhibitory concentration data , the uterine tissue concentrations of moxifloxacin achieved over 24 hours would be sufficient to eradicate the range of bacterial pathogens responsible for PID .
