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
objectiveTo evaluate the safety and efficacy of stent-assisted coiling (SAC) and non-stent-assisted coiling (NSAC) in the treatment of wide-neck intracranial aneurysms (WNAs).
methodsA meta-analysis was conducted to compare SAC and NSAC in treating WNAs. Primary outcomes were aneurysm occlusion rates and perioperative complication rates.
resultsA total of 11 studies were included in this meta-analysis, encompassing 964 patients, with 547 assigned to the SAC group and 417 to the NSAC group. The SAC group demonstrated a significantly higher long-term complete occlusion rate (RR = 1.41, 95% CI [1.18, 1.68], p < 0.001) compared to the NSAC group. Additionally, the aneurysm recurrence rate was significantly lower in the SAC group (RR = 0.41, 95% CI [0.30, 0.56], p < 0.001). However, the SAC group exhibited a significantly higher incidence of ischemic complications (RR = 2.00, 95% CI [1.37, 2.94], p < 0.001), underscoring the increased risks associated with this treatment modality. When comparing the SAC group to the balloon-assisted coiling (BAC) and dual microcatheter coiling (DMC) groups, SAC demonstrated a significant advantage only in terms of recurrence rates: BAC (RR = 0.53, 95% CI [0.30, 0.92], p = 0.025) and DMC (RR = 0.49, 95% CI [0.30, 0.80], p = 0.004). In patients with ruptured aneurysms, the SAC group achieved a significantly higher complete occlusion rate (RR = 1.35, 95% CI [1.15, 1.59], p < 0.001) and a notably lower recurrence rate (RR = 0.29, 95% CI [0.15, 0.56], p < 0.001). Despite these positive outcomes, the overall complication risk (RR = 1.35, 95% CI [1.03, 1.78], p = 0.031) and the risk of ischemic complications (RR = 2.23, 95% CI [1.43, 3.46], p < 0.001) were significantly higher in the SAC group compared to the NSAC group.
conclusionsSAC provides superior long-term occlusion rates for RIA but is associated with higher perioperative ischemic complications than NSAC. Although it lowers recurrence compared to BAC and DMC, it may not be suitable for all patients.
