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
The long-term efficacy of clipping unruptured intracranial aneurysms via various keyhole mini-craniotomy procedures was evaluated. A retrospective review was conducted on 350 unruptured intracranial aneurysms (6.1 ± 1.9 mm) in 330 patients (218 women and 112 men, mean age 62 ± 10 years) located in the anterior circulation and clipped via various keyhole mini-craniotomy procedures between July 2005 and December 2023. modified Rankin Scale and Mini-Mental State Examination were evaluated. Anxiety and depression were assessed using the Beck Depression Inventory and the Hamilton Rating Scale for Depression. The state of clipping was assessed by computed tomography angiography at 1 year and at intervals of a few years. The mean size of the craniotomy was 26.5 ± 3.4 mm and the complete neck clipping rate was 96.9%. The mean postoperative hospitalization was 2.7 ± 3.6 days. Two patients (0.6%) experienced symptomatic lacunar infarctions. Surgical morbidity (modified Rankin Scale >2 or Mini-Mental State Examination <24) at 3 months, 1 year, and at the last examination (mean 6.6 ± 4.4 years) was 0.9%, 1.5%, and 1.8%, respectively. Neither neurological state nor cognitive function changed significantly during the follow-up period. Anxiety and depression states improved significantly at 3 months after surgery. During radiological follow up (mean 7.1 ± 4.6 years, range 1-19 years), the rates of regrowth of aneurysm remnant, recurrence, retreatment, and rupture were 18.1% (1.6%/year), 0.9% (0.1%/year), 0.9% (0.1%/year), and 0.3% (0.04%/year), respectively. Our study confirmed that keyhole clipping of unruptured intracranial aneurysm had low morbidity, early recovery in anxiety and depression, and very low aneurysm recurrence and retreatment rates, indicating that this modality is substantially curative.
