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
introductionThe aim of this study was to evaluate the feasibility of endovascular treatment (EVT) for ruptured very small (≤5 mm) or tiny (≤3 mm) paraclinoid aneurysms of the internal carotid artery (ICA).
methodsFrom November 2009 to April 2012, 32 ruptured paraclinoid aneurysms (very small, 23; tiny, 9) in 31 patients received EVT. Angiographic follow-up determined occlusion rates which were classified as total/near-total (95-100 %), subtotal (80-95 %), and partial (<80 %) occlusions. Follow-up data were retrospectively analyzed and categorized using the Modified Rankin Scale (mRS).
resultsBased on our paraclinoid aneurysm classification, 25 % (8) were classified as type I, 46.9 % (15) as type II, and 28.1 % (9) as type III. EVT was technically successful in 96.8 % (31), with coiling only in 12.5 % (4), balloon remolding coiling in 6.3 % (2), and stent-assisted coiling in 78.1 % (25). Total/near-total occlusion was immediately achieved in 34.4 % (11), subtotal occlusion in 37.5 % (12), and partial occlusion in 28.1 % (9). Follow-up angiography (mean, 9.9 ± 6.4 months) revealed total/near-total occlusion in 50 % (16) aneurysms, subtotal in 31.3 % (10), and partial occlusion in 18.8 % (6). At the end of clinical follow-up (mean, 14.8 ± 9.5 months), it revealed an mRS grade 0 in 38.7 % (12) of patients, grade 1 in 25.8 % (8), grade 2 in 22.6 % (7), grade 3 in 6.5 % (2), grade 4 in 3.2 % (1), and grade 5 in 3.2 % (1).
conclusionEVT is feasible and effective for ruptured very small or tiny paraclinoid aneurysms of the ICA.
