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

Although endovascular therapy has been proven safe and has become in many centers the primary method of treatment for intracranial aneurysms, the long-term durability of endovascular embolization remains a concern; at least for some aneurysms despite initial good result. While healing after clipping relies on mechanical occlusion, restoration after endovascular occlusion mainly requires the induction of a biological response. Healing after embolization depends on the growth of new tissue over the thrombus formed by the embolization material, or alternatively, on the organization of thrombus into fibrous tissue. This review highlights the fundamental importance of aneurysm wall biology on the healing process and long-term occlusion after intracranial aneurysm (IA) treatment. It seems likely that the effect of luminal thrombus on the IA wall, as well as the IA wall condition at the time of thrombosis, determine if thrombus organizes into scar tissue (neointima formation by infiltration of cells originating from the IA wall) or if the wall undergoes continuous remodeling, which is primarily destructive (loss of mural cells). In the latter, intraluminal thrombus organization fails and the impaired healing increases the chance of recurrence. Mechanisms underlying IA reopening, the influence of intraluminal thrombosis on the IA wall, and clinical implications of the IA wall condition are discussed in detail, along with how knowledge of IA wall biology can offer new solutions for IA treatment and affect the patient selection for and follow-up after endovascular treatment.
