Malperfusion on Presentation Versus Complexity of Operation as Determinants of Early Mortality in Acute Type A Aortic Dissection.

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
Background: Degree of malperfusion on presentation is a known determinant of early mortality in acute Type A aortic dissection (TAAD). Its prediction of mortality when stratified by complexity of central repair has not been well-described. Methods: Over a 6-year period, 183 patients had a central repair for TAAD, 146 of whom had a spontaneous etiology and an acute presentation (≤14 days). Each patient was assigned a Penn Class based on ischemia (malperfusion): A-none, B-regional, or C-global. The index operation was identified as simple (ascending aorta and/or hemiarch replacement) or complex (concomitant root replacement, arch replacement, or coronary artery bypass grafting). Early mortality was defined as in-hospital or within 30 days of surgery, if discharged. Results: The overall early mortality was 10.3% (15/146), and it was significantly different in each Penn Class: 1.5% (1/65) for A, 8.7% (4/46) for B, 22.8% (8/35) for C ( Conclusion: In spontaneous acute TAAD, degree of malperfusion on presentation, rather than operative complexity, was the dominant factor in early mortality.
