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

A synthetic gene encoding an anti-phytochrome single-chain Fv (scFv) antibody bearing an N-terminal signal peptide has been used to transform tobacco plants. Immunoblot analysis showed that transformed plants accumulate high levels of scFv protein, accounting for up to 0.5% of the total soluble protein fraction, which could be extracted by simple infiltration and centrifugation of leaf tissue. A substantial proportion of the scFv protein extracted in this way was found to possess antigen-binding activity. Callus cell suspension cultures derived from transformed plants secrete functional scFv protein into the surrounding medium. Compared with the levels of scFv protein observed in plants expressing the native scFv gene, the incorporation of an N-terminal signal peptide, to target the scFv to the apoplast, results in elevated accumulation of the protein.
