Immobilization as a technical possibility for long-term storage of bacterial biosensors.
Article in Radiation and environmental biophysics, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
For applications in field experiments, the recombinant strain Salmonella typhimurium TA1535 was immobilized to permit its immediate utilization after long storage periods. Salmonella typhimurium TA1535 cells contain the plasmid that has an inducible SOS promoter fused to a promoterless luxCDABFE operon from Photobacterium leiognathi. The induction of bioluminescence occurs in the presence of the DNA-damaging agent mitomycin C which stimulates the bacterial SOS response. Early stationary phase cells were immobilized at a cell concentration of 10(10) CFU/ml in microtiter plates and stored up to 6 weeks at 4 degrees C in a sealed container. Even after 4 weeks of storage, the bioluminescence kinetics and yield in response to different concentrations of mitomycin C were not significantly different from those of freshly prepared samples.
