Growth rates and rRNA content of four marine bacteria in pure cultures and in the Delaware estuary.
Article in The ISME journal, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 32 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
Interpretation of 16S ribosomal RNA (rRNA) to 16S rRNA gene ratios (rRNA:rDNA) is based on a limited number of studies with rapidly growing copiotrophic bacteria. The most abundant bacteria in the ocean are oligotrophs, which probably grow more slowly than those bacteria whose rRNA:rDNA versus growth rate relationships are known. To examine whether rRNA:rDNA varies differently in oligotrophic marine bacteria than in copiotrophic bacteria, we used quantitative PCR and reverse transcriptase quantitative PCR to measure rRNA:rDNA in two marine copiotrophs and in two marine oligotrophs, including Candidatus Pelagibacter ubique HTCC1062, a coastal isolate of SAR11, the most abundant bacterial clade in the ocean. The rRNA:rDNA ratios for the two copiotrophs were similar to those expected on the basis of an analysis of previously studied copiotrophic bacteria, while the ratios for the two oligotrophs were substantially lower than predicted even given their slow growth rates. The rRNA:rDNA ratios determined along a transect in the Delaware estuary suggested that SAR11 bacteria grow at rates close to the growth rate in culture, while rates of the two copiotrophs were far below those observed in laboratory cultures. Our results have implications for interpreting rRNA:rDNA from natural communities, understanding growth strategies and comparing regulatory mechanisms in copiotrophs and oligotrophs.
