Development and Validation of the Partially-automated Needle Direction Assistant (PANDA) for CT-guided Interventions.

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
Purpose: A newly developed device, the Partially Automated Needle Direction Assistant, was designed to assist with computed tomography-guided oblique needle puncture. This device allows operators to accurately and in real-time determine the puncture angle based on the target lesion and needle entry point. The purpose of this report is to introduce the concept of Partially Automated Needle Direction Assistant and present results from an initial phantom study. Material and Methods: Partially Automated Needle Direction Assistant integrates a 9-axis internal measurement unit for angle detection, transmitting real-time orientation data to a tablet application via Wi-Fi. Operators align the needle direction with a displayed guideline. A phantom study was conducted with two operators of differing interventional radiology experience levels (operator A: 1 year; operator B: 4 years) performing needle punctures into embedded targets. Success rates were evaluated based on a scoring system reflecting needle placement accuracy. Results: Both operators successfully punctured all six sites, achieving a 100% success rate. Center hits were not influenced by target size, puncture direction, or operator experience level. Operator A tended to achieve higher scores than operator B (mean scores: 1.50 vs. 1.17; p = 0.073). Conclusions: Partially Automated Needle Direction Assistant demonstrated high accuracy and usability in guiding oblique needle punctures, regardless of operator experience. This device has the potential to enhance safety, reduce radiation exposure, and streamline computed tomography-guided interventions.
