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

Electroporation (EP) transiently increases cell membrane permeability through the application of controlled electric pulses. Bipolar needle electrodes have been developed to simplify EP procedures by reducing the number of electrode insertions while improving control of electric field geometry and spatial confinement. This technical note describes the design principles, electric field behavior, and image-guided implementation of single-needle bipolar electrodes for EP applications in both soft and bone tissues. Electric field simulations and preclinical investigations were performed to assess field distribution, safety, and tissue selectivity. The practical implementation of the bipolar configuration is illustrated through representative image-guided examples from multiple institutions across different anatomical settings. The single-needle design enables minimally invasive procedures with predictable field control and limited extension to surrounding structures, even in anatomically complex or previously treated regions. Overall, bipolar electrodes represent a versatile and reproducible technological solution for electroporation-based treatments, supporting precise and tissue-sparing image-guided interventions.
