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

backgroundThe Flow Re-Direction Endoluminal Device X (FRED

methodsA literature search was performed in four electronic databases, PubMed/MEDLINE, Embase, Google Scholar, and Web of Science, for studies that evaluated FRED-X in managing intracranial aneurysms. Proportions were pooled employing the inverse variance method, and binary outcomes were analyzed using odds ratio (OR) and 95% confidence interval (CI). The primary outcome was an aneurysm occlusion at the final follow-up.

resultsEight studies involving 480 patients and 531 aneurysms were included. Most patients were female (81.5%), with a mean age of 56.2 years. Most aneurysms were unruptured (84.1%, 95%CI = 66% - 96.5%) and located in the anterior circulation (86.7%, 95%CI = 75.9% - 94.8%), primarily in the internal carotid artery (64.2%). Procedural data showed a mean procedure time of 68.2 (SD = 38.1) minutes and a fluoroscopy time of 23.5 (SD = 11.7) minutes. The mean aneurysm size was 6.4 mm (SD = 5.1). In-stent stenosis occurred in 1.2% of cases. Adequate occlusion was achieved in 85.9% (95%CI = 79% - 91.8%) of patients at the last follow-up. Symptomatic complications occurred in 4% (95%CI = 0.7% - 9%) of patients, and the overall mortality rate was 0.34% (95%CI = 0.0% - 1.7%).

conclusionThe FRED-X flow diverter is safe and effective in treating intracranial aneurysms. It has low complication rates, minimal in-stent stenosis, and efficient procedural metrics. Long-term studies must confirm its durability and potential for broader applications.
