Treatment of saccular wide-neck intracranial aneurysm using Leo baby stent: a single-center experience based on 156 cases.
Article in Neurosurgical review, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
To describe the mid-term safety and efficacy of Leo baby stent applied in saccular wide-neck intracranial aneurysms (IAs). 151 patients harboring 156 IAs treated with Leo baby stent from March 2021 to October 2023 were enrolled for further analysis. Among 156 IAs, 142 cases (91.0%) received one single Leo baby stent deployment while 14 cases (9.0%) received dual stents deployment. Stent-assisted coiling strategy was applied in all cases and the success rate was 100%. Immediate IAs occlusion results showed that 48 cases (30.8%) obtained Raymond grade I, 39 cases (25.0%) obtained Raymond grade II and 69 cases (44.2%) obtained Raymond grade III. Perioperative complications occurred in 10 cases (6.4%). Overall morbidity rate was 3.5% and mortality rate was 0% during follow-up. Clinical follow-up was available in 141 patients (93.4%). 136 patients (96.5%) got favorable clinical prognosis (mRS score 0-2) while 5 patients (3.5%) were in a poor neurological condition (mRS score 3-6). Angiographic follow-up was available in 136 cases (87.2%). The results showed that Raymond grade I was obtained in 112 cases (82.4%), Raymond grade II was obtained in 11 cases (8.1%) and Raymond grade III was obtained in 13 cases (9.6%). 4 cases (2.9%) were confirmed with IAs recurrence and received retreatment. Asymptomatic in-stent stenosis was detected in 8 patients (5.9%). The results demonstrate that stent-assisted coiling using Leo baby stent with favorable IAs embolization rate and the low complication rate is a feasible way in treating complex IAs.
