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
We present a novel triple-catheter adjunctive technique through a 6-Fr distal access catheter (DAC) for coil embolisation of an 18 mm wide-necked splenic aneurysm located at the bifurcation of the superior and inferior branches in a 63-year-old female. Despite the significantly tortuous splenic artery, the DAC was successfully navigated near the aneurysm, providing catheter stability. One 2.8-Fr balloon catheter and 2 2.2-Fr microcatheters were deployed simultaneously through the DAC to perform the balloon-assisted double-catheter technique. Dense packing was achieved with a volume embolisation ratio of 39.2%, while preserving the superior branch flow. Post-embolisation angiography revealed complete aneurysmal occlusion without splenic infarction. This technique presents a viable solution for complex visceral aneurysms in tortuous anatomies, enabling dense packing while preserving the parent artery, without requiring multiple access sites or larger guiding catheters.
