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

Cell permeabilization by electric pulses (EP), or electroporation, is widely used for intracellular delivery of drugs and plasmids, as well as for tumour and tissue ablation. We found that cells pre-treated with 100-μs EP develop delayed hypersensitivity to subsequent EP applications. Sensitizing B16 and CHO cells by splitting a single train of eight 100-μs EP into two trains of four EP each (with 5-min. interval) decreased the LD(50) 1.5-2 times. Sensitization profoundly enhanced the electroporation-assisted uptake of bleomycin, a cell-impermeable cytotoxic agent accepted for killing tumours by electrochemotherapy. EP exposures that were not lethal per se caused cell death in the presence of bleomycin and proportionally to its concentration. Sensitizing cells by a split-dose EP exposure increased bleomycin-mediated lethality to the same extent as a 10-fold increase in bleomycin concentration when using a single EP dose. Likewise, sensitization by a split-dose EP exposure (without changing the overall dose, pulse number, or amplitude) enhanced the electroporative uptake of propidium up to fivefold. Enhancement of the electroporative uptake appears a key mechanism of electrosensitization and may benefit electrochemotherapy and numerous applications that employ EP for cell permeabilization.
