1 · What the graph read from it

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.

2 · The registry

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

Coalbed methane enhancement technologies are critical for clean and efficient utilization of low-rank coal resources. However, current biological conversion efficiencies remain limited because of low electron transfer rates and insufficient activity of methanogenic bacteria. In this study, a synergistic enhancement strategy combining pyrite addition and electrical stimulation was proposed to improve methane production from brown coal during anaerobic fermentation by promoting microbial electron transport and metabolic activity. Gradient experiments were conducted under varying pyrite dosages (0-32%) and voltage conditions (0-6 V), coupled with 16S rRNA high-throughput sequencing to systematically analyze gas production, key physicochemical parameters, and microbial community shifts. The results indicated that the combined treatment (16% pyrite + 3 V) increased the cumulative methane yield to 4220 mL over a 30 day fermentation period, representing a 767% increase compared with the untreated control. Concurrently, the relative abundance of
