Multiplex gene transfer by genetic transformation between isolated S. pneumoniae cells confined in microfluidic droplets.
Article in Integrative biology : quantitative biosciences from nano to macro, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Gene exchange via genetic transformation makes major contributions to antibiotic resistance of the human pathogen, Streptococcus pneumoniae (pneumococcus). The transfers begin when a pneumococcal cell, in a transient specialized physiological state called competence, attacks and lyses another cell, takes up fragments of the liberated DNA, and integrates divergent genes into its genome. Recently, it has been demonstrated that the pneumococcal cells can be enclosed in femtoliter-scale droplets for study of the transformation mechanism, offering the ability to characterize individual cell-cell interactions and overcome the limitations of current methods involving bulk mixed cultures. To determine the relevance and reliability of this new method for study of bacterial genetic transformation, we compared recombination events occurring in 44 recombinants recovered after competence-mediated gene exchange between pairs of cells confined in femtoliter-scale droplets vs. those occurring in exchanges in parallel bulk culture mixtures. The pattern of recombination events in both contexts exhibited the hallmarks of the macro-recombination exchanges previously observed within the more complex natural contexts of biofilms and long-term evolution in the human host.
