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

To evaluate the safety and efficacy of staged coiling followed by flow diverter (FD) in the treatment of ruptured intracranial aneurysms(RIAs). A retrospective analysis was conducted on 20 patients with RIAs treated with staged coiling followed by FD at a single center, between April 2015 and September 2024. Patient demographics, aneurysm characteristics, clinical and imaging outcomes were reviewed. Aneurysm occlusion was determined using the O'Kelly-Marotta (OKM) grading system. All 20 RIAs underwent successful first-stage coiling. In the second stage, 21 FD were deployed, achieving a 100% success rate. The mean maximum diameter of aneurysms was 10.2 (6.3, 20.7) mm, with a neck width of 6.1 (4.2, 7.8) mm. The interval between the first and second stages was 33.3 ± 23 days. One patient (5%) experienced ischemic complications during the first-stage coiling, but no hemorrhagic complications occurred. In the second stage, FD placement was performed without any hemorrhagic or ischemic complications. All 20 patients (100%) received clinical follow-up with a median follow-up time of 182(172.5,190.5) days.14 patients(70%) underwent available DSA follow-up with a median follow-up time of 184 (158.3, 194.8) days, and the OKM grade B was reported in 1 case (7.1%), grade C in 1 case (7.1%), and grade D in 12 cases (85.7%). No aneurysm recurrence was observed. At the last follow-up, all 20 patients had an mRS score of ≤ 1. Staged coiling followed by FD placement for the treatment of RIAs is a safe and effective approach, with a high technical success rate, low perioperative complication rate, and high aneurysm occlusion rate during follow-up.
