Investigating cell autonomy in microorganisms.
Article in Current genetics, 2022. 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
Cell-cell signaling in microorganisms is still poorly characterized. In this Methods paper, we describe a genetic procedure for detecting cell-nonautonomous genetic effects, and in particular cell-cell signaling, termed the chimeric colony assay (CCA). The CCA measures the effect of a gene on a biological response in a neighboring cell. This assay can measure cell autonomy for range of biological activities including transcript or protein accumulation, subcellular localization, and cell differentiation. To date, the CCA has been used exclusively to investigate colony patterning in the budding yeast Saccharomyces cerevisiae. To demonstrate the wider potential of the assay, we applied this assay to two other systems: the effect of Grr1 on glucose repression of GAL1 transcription in yeast and the effect of rpsL on stop-codon translational readthrough in Escherichia coli. We also describe variations of the standard CCA that address specific aspects of cell-cell signaling, and we delineate essential controls for this assay. Finally, we discuss complementary approaches to the CCA. Taken together, this Methods paper demonstrates how genetic assays can reveal and explore the roles of cell-cell signaling in microbial processes.
