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:

Outcomes in patients with diabetes mellitus undergoing percutaneous coronary intervention in the current era : a report from the Prevention of REStenosis with Tranilast and its Outcomes ( PRESTO ) trial . BACKGROUND Diabetes portends an adverse prognosis in patients undergoing percutaneous coronary intervention ( PCI ) . Whether improvements in current clinical practice ( stents , IIb/IIIa antagonists ) have resulted in substantial improvement of these outcomes remains an issue . The aim of this study was to determine the influence of diabetes on 9-month outcomes of patients undergoing PCI in the current era . METHODS AND RESULTS The 11 482 patients enrolled in the Prevention of REStenosis with Tranilast and its Outcomes ( PRESTO ) Trial were stratified according to the presence ( n=2694 ) or absence ( n=8798 ) of diabetes . Diabetic patients were older ; were more likely to be female ; had a higher proportion of congestive failure , hypertension , prior CABG , and unstable angina ; and had higher body mass index and lower ejection fraction than nondiabetic patients ( P < 0.01 for all comparisons ) . The degree of multivessel disease was similar between the two groups . American College of Cardiology/American Heart Association type C lesions were more common in diabetic patients ( 17 % versus 15 % , P < 0.01 ) . Angiographic and procedural success rates and in-hospital events were similar between the two groups . The primary end point of death , myocardial infarction , or target vessel revascularization ( TVR ) was analyzed as time-to-first event within 9 months of the index PCI . After adjusting for certain baseline characteristics , diabetes was independently associated with death at 9 months ( relative risk [ RR ] , 1.87 ; 95 % CI , 1.31 to 2.68 , P < 0.01 ) and with an increased likelihood of TVR ( RR , 1.27 ; 95 % CI , 1.14 to 1.42 , P < 0.01 ) , as well as the composite end point of death/myocardial infarction/TVR ( RR , 1.26 ; 95 % CI , 1.13 to 1.40 , P < 0.01 ) . CONCLUSIONS Despite advances in interventional techniques , diabetes remains a significant independent predictor of adverse events in the intermediate term after PCI .
