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

Tetracycline-inducible HEK293S stable cell lines have been prepared that express high levels (up to 10 mg/liter) of WT opsin and its mutants only in response to the addition of tetracycline and sodium butyrate. The cell lines were prepared by stable transfection of HEK293S-TetR cells with expression plasmids that contained the opsin gene downstream of a cytomegalovirus promoter containing tetO sequences as well as the neomycin resistance gene under control of the weak H(2)L(d) promoter. The inducible system is particularly suited for overcoming problems with toxicity either due to the addition of toxic compounds, for example, tunicamycin, to the growth medium or due to the expressed protein products. By optimization of cell growth conditions in a bioreactor, WT opsin, a constitutively active opsin mutant, E113Q/E134Q/M257Y, presumed to be toxic to the cells, and nonglycosylated WT opsin obtained by growth in the presence of tunicamycin have been prepared in amounts of several milligrams per liter of culture medium.
