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

The protochordate Ciona has recently become an important model organism for the study of developmental gene regulation, in part because transient transgenic embryos can be produced rapidly and reliably using electroporation. Published methods are currently for the use of electroporation devices delivering exponentially decaying pulses. However, some workers have advocated the use of square wave electroporation devices for eukaryotic transgenics. This paper presents results of experiments to find optimal conditions for the use of square-wave electroporation in the ascidian Ciona. In the present analysis, a single pulse of 90 msec duration at 63-75 V/cm was found to give an optimal balance of a high proportion of cells transformed with the transgene, and a low level of abnormal development. Forty micrograms of DNA per electroporation is sufficient for effective visualization of reporter gene expression, although doses up to 100 μg provide higher proportions of transformed cells. In side-by-side comparison with exponential pulse electroporation, square wave pulses give similar penetrance of transgene expression, along with lower proportions of embryos with abnormal development at higher amounts of input DNA.
