Safety/Efficacy of a Pusher, Thermal Detachment Coil for Ruptured Intracranial Aneurysms: A Multicenter Real-World Study.
Article in Journal of neuroimaging : official journal of the American Society of Neuroimaging. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
background and purposeOptima coils are a new type of embolic coils with complex and WAVE shape properties and variable degrees of softness. In patients with ruptured intracranial aneurysms, we examined the safety (periprocedural complications) and efficacy (occlusion rate immediately postprocedure) of the Optima coil.
methodsWe studied 103 consecutive patients with ruptured intracranial aneurysms who were treated exclusively with the Optima coil, without the use of accompanying implanted devices, at five centers in Spain. Endovascular techniques included stand-alone or balloon-assisted coiling. Postprocedural occlusion and periprocedural device-related adverse events were the endpoints. Aneurysm occlusion was graded according to the modified Raymond-Roy Occlusion scale.
resultsOf the 103 enrolled patients (70 female; median age 59 years), 59 (57.3%) presented with an IV Fischer Scale grade, and 61 (59.2%) of the ruptured aneurysms were wide-necked. Thirty-eight (36.9%) aneurysms were located in the anterior communicating artery. Simple-coiling and balloon-assisted coiling were performed in 36 (34.9%) and 65 (63.1%) patients, respectively. Raymond-Roy Class I, II, and III were reached in 64 (60.3%), 29 (28.1%), and ten (9.7%) following the procedure. The periprocedural device-related serious adverse event rate was 12 (13.5%), of which eight (7.7%) were due to coil protrusion. Four (3.8%) patients had intraprocedural aneurysm rupture. No early rebleeding or death was reported.
conclusionThis analysis suggests that the Optima coil is safe and effective for treating ruptured aneurysms, with satisfactory occlusion rates and low rates of periprocedural device-related serious adverse events.
