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

Objective: To study the safety and reproducibility of high-voltage integrated nanosecond pulse irreversible electroporation (INSPIRE) administered through a single applicator and grounding pad approach in a healthy liver model. Methods: A percutaneous approach to the liver was made under ultrasound guidance in female pigs weighing between 25 and 35 kg. INSPIRE treatments at 3000 V, 4500 V, and 6000 V using 1000 ns or 2000 ns waveforms, with a 0.02 s dose and a 45°C temperature set point were delivered using an actively cooled single applicator and distal grounding pad. Ablation size, muscle stimulation, and cardiac safety were evaluated. Results: All INSPIRE treatments were completed successfully without cardiac synchronization or break-through muscle stimulation. Ablations were visible on ultrasound shortly after treatments were complete. Treatments were completed within approximately 2-8 minutes. The largest ablations, achieved with the 2000 ns waveform at 6000 V, measured 4.4 ± 0.7 cm by 2.9 ± 0.1 cm. Conclusion: INSPIRE can be safely used to achieve significantly larger ablations significantly faster than current irreversible electroporation (IRE) technologies using a simplified single-applicator and grounding pad approach. Significance: INSPIRE overcomes technical and procedural challenges facing IRE including ablation size limitations, muscle stimulation, the need for cardiac synchronization, long procedure times, and the lack of visualization during procedures.
