1 · What the graph read from 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.

2 · The registry

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

False lumen evolution in type B aortic dissection, particularly with medical management and anticoagulation, remains incompletely understood. We report a 55-year-old man on apixaban for pulmonary embolism with a subacute zone 3-10L TBAD without malperfusion. He was managed medically initially and represented twice over 2 months with back pain and acute right lower extremity ischemia. Serial imaging demonstrated dynamic remodeling with progression from partial to near-complete thrombosis to full reperfusion with true lumen compression. Urgent endovascular repair was performed successfully. This case illustrates the unpredictable course of medically managed TBAD and need for judicious use of anticoagulation.
