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
backgroundGuidelines on myocardial infarction (MI) recommend antithrombotic and anticoagulatory treatment at time of diagnosis. MI with ST segment elevation (STEMI) is mostly a certain diagnosis. Acute coronary syndrome without ST segment elevation (NSTE-ACS) has diagnostic uncertainty and remains a working diagnosis in the prehospital setting.
objectiveAssessment of prehospital loading with aspirin and heparin depending on ACS subtype and pretreatment with oral anticoagulants.
methodsThe PRELOAD survey was a nationwide German study. STEMI/NSTE-ACS scenarios were designed and varied in pretreatment: I) no pretreatment, II) new oral anticoagulants (NOAC), III) vitamin K antagonist (VKA). Loading strategy was assessed and included: a) aspirin (ASA), b) unfractionated heparin (UFH), c) ASA + UFH, d) no loading.
resultsA total of 708 emergency physicians were included. In NSTE-ACS without pretreatment, 79% chose loading (p < 0.001). ASA + UFH (71.4%) was the preferred option. In corresponding STEMI scenario, 100% chose loading and 98.6% preferred ASA + UFH (p < 0.001). In NSTE-ACS with NOAC pretreatment, 69.8% favored loading (p < 0.001); in VKA pretreatment the corresponding rate was 72.3% (p < 0.001). In each scenario, ASA was the preferred option. In STEMI with NOAC pretreatment, 97.5% chose loading (p < 0.001); analogous rate was 96.8% in STEMI with VKA pretreatment (p < 0.001). ASA was the preferred option again.
conclusionsPrehospital loading was the preferred treatment strategy despite the diagnostic uncertainty in NSTE-ACS and guidelines recommending loading at time of diagnosis. Pretreatment with oral anticoagulants resulted in a strategy shift to loading with only aspirin. In STEMI patients, this indicates potential undertreatment.
