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

Bicistronic expression vectors have been widely used for co-expression studies since the initial discovery of the internal ribosome entry site (IRES) about 25 years ago. IRES sequences allow the 5' cap-independent initiation of translation of multiple genes on a single messenger RNA strand. Using a commercially available mammalian expression vector containing an IRES sequence with a 3' green fluorescent protein fluorescent marker, we found that sequence length of the gene of interest expressed 5' of the IRES site influences both expression of the 3' fluorescent marker and overall transfection efficiency of the vector construct. Furthermore, we generated a novel construct expressing two distinct fluorescent markers and found that high expression of one gene can lower expression of the other. Observations from this study indicate that caution is warranted in the design of experiments utilizing an IRES system with a short 5' gene of interest sequence (<300 bp), selection of single cells based on the expression profile of the 3' optogenetic fluorescent marker, and assumptions made during data analysis.
