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 purposeAn infrequent occurrence during endovascular treatment is protusion of detachable coils into the parent lumen with a subsequent thrombosis within in the parent vessel or embolic events. We report the short- and intermediate-term angiographic and clinical outcomes of patients who experience coil or loop protrusions and are managed with medical or additional endovascular treatments. MATERIALS AND
methodsThe coil protrusions were identified by retrospective review of 256 consecutive patients treated at 3 centers with endovascular embolizations for intracranial aneurysms and subsequently categorized as grade I when a single loop or coil protruded into the parent vessel lumen less than half the parent artery diameter; grades II and III were assigned when a single coil or loop protruded more than half the parent artery diameter, respectively.
resultsThere were 19 patients with grade I (n = 9), grade II (n = 4), or grade III (n = 6) coil protrusions. Patients with active hemodynamic compromise (n = 6) had intracranial stents placed in addition to aspirin (indefinitely) and clopidogrel (range, 1-12 months; mean, 4.5 months) treatment. The remaining patients were placed on aspirin indefinitely. Complete aneurysm obliteration was achieved in all patients except in 3 in whom near-complete obliteration was achieved. Two patients had intraprocedural aneurysm ruptures, both of whom survived hospitalization. There were 4 deaths (4-21 days), all due to major strokes in different vascular distributions related to vasospasm (unrelated to the coil protrusion).
conclusionsManagement of coil protrusions with antiplatelet therapy and placement of stents (in selected patients) appears efficacious in preventing vessel thrombosis.
