Structural and Maceral Controls on Biogenic Methane Generation: Insights from Vitrain-Durain Separation across the First Coalification Jump.
Article in ACS omega, 2026. 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
Biogenic coalbed methane resources are widely distributed in high-volatile bituminous coal areas, yet the controlling effect of the first coalification jump on biogas generation remains unclear. To explore the combined controlling effects of coal macerals and metamorphic degree on biogenic methane production potential, five coal samples with different metamorphic grades near the first coalification jump were selected. Vitrain and durain fractions were separated from the samples to conduct microbial degradation and methanogenesis experiments. The results show that the methane production yield of vitrain (11.96-15.75 μmol/g) is generally higher than that of durain (4.14-15.49 μmol/g). The methane production of both vitrain and durain presents a general
