Indication and short-term clinical outcomes of high-risk percutaneous coronary intervention with microaxial Impella® pump: results from the German Impella® registry.
Observational study in Clinical research in cardiology : official journal of the German Cardiac Society, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 1 of them a synthesis that pooled it.
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
backgroundPercutaneous coronary intervention (PCI) is an alternative strategy to coronary artery bypass grafting (CABG) in patients with high perioperative risk. The microaxial Impella
methodsThe study is an observational, retrospective multi-center registry. Patients from nine tertiary hospitals in Germany, who have undergone protected high-risk PCI, are included in the present study.
resultsA total of 154 patients (mean age 72.6-10.8 years, 75.3% male) were enrolled. The majority were at a high operative risk illustrated by a logistic EuroSCORE of 14.7-17.4. The initial SYNTAX score was 32.0-13.3, indicating very complex CAD and could be reduced to 14.1-14.3 (p < 0.0001) after PCI. The main reasons for protected PCI were complex coronary anatomy (70.8%), personal impression (56.5%), reduced ventricular ejection fraction (49.4%), comorbidities (47.4%), and surgical turndown (30.5%). Four patients (2.6%) experienced an intrahospital death.
conclusionsData from the study show that protected PCI is a safe and effective approach to revascularize high-risk patients with complex coronary anatomy and comorbidities.
