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
Background: The occurrence rate of distal anterior cerebral artery (DACA) aneurysms is relatively low, primarily due to their deep-seated location, which makes surgical clamping challenging. The objective of this study was to investigate the efficacy and safety of computed tomography (CT) navigation-assisted clipping of DACA aneurysms compared to traditional clipping without navigation. Methods: A retrospective cohort study involving retrospective data collection was performed. The retrospective analysis was conducted on 139 patients with ruptured DACA aneurysms who underwent clipping. From January 2013 to November 2021, 164 patients were retrieved at the Department of Neurosurgery, Renmin Hospital of Wuhan University. The inclusion criteria were patients diagnosed with DACA aneurysms via CT angiography (CTA) or digital subtraction angiography (DSA), those with complete clinical data, and those who underwent craniotomy for aneurysm clipping. Meanwhile, the exclusion criteria were as follows: aneurysm recurrence, traumatic brain injury or surgery history, blood disorders or recent anticoagulant use, and severe organ dysfunction. Data on gender, age, Hunt-Hess grade, Fisher grade, modified Rankin Scale (mRS) score, aneurysm location, hospitalization time, aneurysm found time (the duration from incision to aneurysm discovery), and intraoperative bleeding volume were collected from medical records and neurosurgical databases. Patients were followed up in the clinic or by telephone in May 2022. All patients were divided into a navigation group or a traditional group for statistical analysis. Results: No statistically significant differences were observed in age, sex, Fisher grade, Hunt-Hess grade, hospitalization time, or aneurysm site between the navigation group and traditional group (P>0.05). Intraoperative blood loss was lower in the navigation group than in the traditional group {370 [280-460] Conclusions: CT neuronavigation-assisted microsurgery for clipping DACA aneurysms may improve surgical accuracy, shorten the time to locate aneurysms, and reduce intraoperative blood loss. Although no significant difference in prognosis was observed, this technique shows promise as a safe and effective alternative to traditional clipping without navigation.
