Trial profile. SAEs indicates severe adverse events.

Effect of packing density and immediate angiographic results. From left to right, decreasing packing density has an impact, but it depends on inferior immediate angiographic results. From upper to lower rows, increasing packing density, given the same initial angiographic results, has no impact on long-term angiographic results.

Effect of packing density and immediate angiographic results. Packing density is better thought of as an index compounding many causal factors, such as aneurysm and neck sizes and immediate angiographic results, rather than a true causal factor in long-term angiographic results.
