Role of tfxE, but not tfxG, in trifolitoxin resistance.
Article in Applied and environmental microbiology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Eight genes, tfxABCDEFG and tfuA, confer production of trifolitoxin (TFX), a ribosomally synthesized, posttranslationally modified peptide antibiotic, in TFX-sensitive alpha-proteobacteria. An in-frame deletion in tfxE significantly reduced a strain's resistance to TFX in comparison to that of an otherwise identical construct containing wild-type tfxE. The deletion of tfxG had no effect on TFX resistance. Nevertheless, RNase protection assays showed that tfxE and tfxG are transcribed, showing that the tfxDEFG mRNA was produced on the same transcript. Examination of the role of tfxG in TFX production showed that the tfxG mutant expressed slightly less TFX activity and produced only one TFX isomer while four are produced by the wild-type strain. Thus, tfxE plays an important role in TFX resistance while tfxG is important in optimal TFX production through the production of TFX isomers.
