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: Frontal ventriculostomy (FV) is essential in neurosurgery; however, traditional freehand puncture methods have low accuracy, and ultrasound guidance is time consuming and expensive. To improve freehand puncture accuracy, this study introduced a biplanar intersection (BI) method, and analyzed the frontal-horn puncture mechanism. No related reports exist to date. Methods: Three-dimensional (3D) computed tomography (CT) reconstruction was performed using data from random patients, aged ≥18 years, who presented with enlarged lateral ventricles, and an Evans index >0.33, and had no signs of ventricular compression, deformation, displacement, or a history of craniectomy. This study was conducted at Fujian Provincial Hospital between May 2022 and May 2023. Using the principles of BI, we determined the location coordinates, and conducted a variance analysis. We simulated the puncture using the BI method and compared it with traditional methods. Differences between groups were evaluated using chi-squared tests and independent samples t-tests. Results: A total of 135 patients (110 males, 25 females; aged 18-78 years) were included in the study. The lateral projection was situated 13.3±1.5 mm anteriorly and 45.7±4.1 mm superiorly in relation to the intersection of the anterior margin of the tragus and the superior margin of the zygomatic arch. The anterior projection was located 13.8±2.4 mm above and 5.5±1.1 mm lateral to the glabella. The mean puncture depth was determined to be 56 mm (48-64 mm). In a sub-analysis of 36 patients, the BI method exhibited a significantly higher optimal puncture rate (36/36 versus 31/36, χ Conclusions: The BI method, which is founded on rigorous mathematical principles, was shown through simulations to have enhanced precision in puncture efficiency. However, further clinical research needs to be conducted to ascertain its effectiveness.
