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

An electroporation procedure has been described for introducing plasmid DNA into Dunaliella salina cells. By this procedure, a bulk of plasmid DNA was delivered into the cells and retained for at least 3 d. Reverse transcriptase polymerase chain reaction (RT-PCR) and sequencing analyses indicated that the transcription and pre-mRNA splicing of ble gene (contributing the Zeocin resistance) were detected in the cells as early as 1 h after the electroporation. Individual colonies could retain the resistance to 10 mg/L Zeocin for at least 6 mo. Subsequent Southern blot analysis showed the existence of introduced plasmid DNA inside these colonies. However, most of the cells (approx 90%) lost the resistance in the presence of 5 mg/L Zeocin during subculturing, which was consistent with the observations of both rearranged and episomal plasmid DNA existed in the cells. Nevertheless, the electroporation procedure allows introducing a gene of interest and studying its expression and function in D. salina cells.
