The Agrobacterium oncogene AB-6b causes a graft-transmissible enation syndrome in tobacco.
Article in Plant molecular biology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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.
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
Agrobacterium 6b oncogenes induce tumours and modify plant growth in various ways. Here we show that the AB-6b gene from strain AB4 placed under 2x35S promoter control (2x35S-AB-6b) induces a complex enation syndrome in transgenic Nicotiana tabacum plants, that also occurs in a few rare cases of genetic enations. In Arabidopsis thaliana, 2x35S-AB-6b induced radially symmetrical tubes on the abaxial side of the leaves, which must therefore be considered as the Arabidopsis equivalents of enations on other plant species. Tobacco and Arabidopsis 2x35S-AB-6b leaves contained small, supernumerary densely packed cells between the spongy mesophyll and the abaxial epidermis, close to vascular strands arising at an early stage of leaf development. On tobacco, the 2x35S-AB-6b enation syndrome could be transmitted across graft junctions to growing tissues of untransformed plants, both acropetally and basipetally. We propose that the AB-6b gene encodes the synthesis of one or more enation factor(s) that are transported by the phloem and modify the growth of developing tissues.
