Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study introduces a low-voltage electroporation microchip designed for transfection in cat embryos, featuring real-time impedance monitoring. The microchip uses a field constriction strategy, which localises the electric field to the membrane region in contact with the micro-orifice, enhancing electroporation efficiency while minimising damage. Embryos were positioned on the orifice, and a series of voltage pulses (10, 15, and 20 V) were applied. Electroporation efficacy was assessed using fluorescent dyes, followed by real-time impedance measurements to monitor the membrane resealing time. It provided valuable insights into membrane recovery times, essential for optimizing gene editing conditions to ensure efficient delivery and maintain cell integrity. The results demonstrated that the microchip with 15 V achieved a 69.5% higher electroporation rate and 100% of survival compared to conventional devices (p < 0.05). Additionally, the microchip successfully facilitated the transfer of green fluorescent protein genes into embryos, achieving a 78.5% success rate significantly greater compared to 53.6% with the conventional device (p < 0.05). This innovative microchip provides transformative transfection technology for safer and more efficient genomic modifications in embryos. It holds promising applications across species and therapeutic interventions, paving the way for future studies in advanced genomic research.
