Identification of ten Anabaena sp. genes that under aerobic conditions are required for growth on dinitrogen but not for growth on fixed nitrogen.
Article in Journal of bacteriology, 2011. 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
Heterocysts are specialized cells required for aerobic fixation of dinitrogen by certain filamentous cyanobacteria. Numerous genes involved in the differentiation and function of heterocysts in Anabaena sp. strain PCC 7120 have been identified by mutagenizing and screening for mutants that require fixed nitrogen for growth in the presence of oxygen. We have verified that 10 Anabaena sp. genes, all1338, all1591, alr1728, all3278, all3520, all3582, all3850, all4019, alr4311, and all4388, identified initially by transposon mutagenesis, are such genes by complementing or reconstructing the original mutation and by determining whether the mutant phenotype might be due to a polar effect of the transposon. Elucidation of the roles of these genes should enhance understanding of heterocyst biology.
