Freshwater Ammonia-Oxidizing Archaea Retain amoA mRNA and 16S rRNA during Ammonia Starvation.
Article in Life (Basel, Switzerland), 2015. 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
In their natural habitats, microorganisms are often exposed to periods of starvation if their substrates for energy generation or other nutrients are limiting. Many microorganisms have developed strategies to adapt to fluctuating nutrients and long-term starvation. In the environment, ammonia oxidizers have to compete with many different organisms for ammonium and are often exposed to long periods of ammonium starvation. We investigated the effect of ammonium starvation on ammonia-oxidizing archaea (AOA) and bacteria (AOB) enriched from freshwater lake sediments. Both AOA and AOB were able to recover even after almost two months of starvation; however, the recovery time differed. AOA and AOB retained their 16S rRNA (ribosomes) throughout the complete starvation period. The AOA retained also a small portion of the mRNA of the ammonia monooxygenase subunit A (amoA) for the complete starvation period. However, after 10 days, no amoA mRNA was detected anymore in the AOB. These results indicate that AOA and AOB are able to survive longer periods of starvation, but might utilize different strategies.
