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 boundaries required for maximal expression from the promoter/leader region of the full length transcript of figwort mosaic virus (FLt promoter) coupled to reporter genes were defined by 5' and 3' deletion analyses. In transient expression assays using protoplasts of Nicotiana edwardsonii, a 314 bp FLt promoter fragment sequence (-249 to +65 from the transcription start site) was sufficient for strong expression activity. Plant expression vectors developed with modified FLt promoters were tested with GUS or CAT as reporter genes in transgenic plants. The FLt promoter is a strong constitutive promoter, with strength comparable to or greater than that of the CaMV 35S promoter. The FLt promoter with its double enhancer domain linked to GUS or CAT reporter genes provides an average 4-fold greater activity than the FLt promoter with a single enhancer domain (-55 to -249 bp upstream fragment) in tests with transgenic plants and in protoplast transient expression assays.
