1 · What the graph read from it

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.

2 · The registry

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

Although many institutions increasingly perform endovascular coiling instead of microsurgical clipping as the primary treatment for ruptured aneurysms, there remains ongoing debate regarding the optimal treatment strategy for ruptured middle cerebral artery (MCA) aneurysms. Therefore, we compared the outcomes of clipping and coiling for treating ruptured MCA aneurysms. A total of 155 ruptured MCA aneurysms that were deemed eligible for both clipping and coiling were retrospectively reviewed. We compared patient characteristics, radiological results, clinical outcomes, and perioperative complications between patients who received clipping and those receiving coiling. Furthermore, we analyzed the potential risk factors for perioperative complications that differed between the two groups. 59 (38.1%) aneurysms were treated using coiling, and 96 (61.9%) received clipping. The clipping group showed a significantly higher rate of immediate complete occlusion and a lower rate of neck remnants compared with the coiling group (p = 0.006). These radiological results persisted at the 12-month angiographic follow-up, with a significantly higher complete occlusion rate (p = 0.038) and a lower recanalization rate (p = 0.033) in the clipping group. The clinical outcomes were comparable between the two groups. Patients treated with coiling showed a higher rate of permanent shunting than those treated with clipping (18.6% vs. 8.3%, p = 0.058). Coiling was independently associated with shunt-dependent hydrocephalus in multivariate analysis. Microsurgical clipping provides comparable clinical outcomes, better occlusion, and superior durability for treating ruptured MCA aneurysms compared with endovascular coiling. Therefore, clipping remains a viable option for treating ruptured MCA aneurysms, even in aneurysms suitable for coiling.
