Assessment of the oxidant tolerance of Methanosarcina acetivorans.
Article in FEMS microbiology letters, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
All methane-producing Archaea (methanogens) are strict anaerobes, but the majority of species are tolerant to oxidants. Methanosarcina species are important environmental and industrial methanogens as they are one of only two genera capable of producing methane with acetate. Importantly, Methanosarcina species appear to be the most oxidant-tolerant; however, the mechanisms underlying this tolerance are poorly understood. We report herein two similar methods (spot-plating and microtiter plate) developed to examine the oxidant tolerance of Methanosarcina acetivorans by viability assessment. Both methods revealed that M. acetivorans can tolerate exposure to millimolar levels of hydrogen peroxide (H2O2 ) without a complete loss of viability. The exogenous addition of catalase was also shown to protect M. acetivorans from H2O2 toxicity, indicating catalase can serve as an antioxidant enzyme in methanogens even though oxygen is a byproduct. Of the two methods, the microtiter plate method provided a simple, reliable, and inexpensive method to assess viability of M. acetivorans. Combined with recent advances in the genetic manipulation of methanogens, methods in assessment of methanogen oxidant tolerance will aid in the identification of components of the antioxidant defense systems.
