Experimental procedures for studying microbial reactions under high hydrogen gas saturations in microcosms.
Article in MethodsX, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This methodology is proposed to investigate the response of microbial communities through analysis of headspace composition under high saturations of hydrogen. Changes in headspace composition will be related to specific communities and environmental conditions that will influence their response and result in changes in gases produced or potential changes in the liquid phase of microcosms pertaining to the hydrogen consumption rate through microbial metabolic processes. A step-by-step procedure is documented here.•Methodology includes an easy setup utilising common laboratory equipment.•The method showed minor appreciable loss of hydrogen from the microcosm setup/storage and the use of exetainers for gas measurements.•Actively studied microbial hydrogen consumption across 18 days at 30 °C and 50 °C This method is useful for the first instances in scientific studies towards understanding species or microbial communities found in environments with high percentages of hydrogen: underground hydrogen storage sites, hydrogen pipelines, and hydrogen leakage into subsurface soils.
