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

In this study, a two-chambered microbial electrolysis cell (MEC) was fabricated using a carbon cloth electrode, a Nafion-117 membrane, and Escherichia coli as the biocatalyst. The system treated sewage sludge with an initial chemical oxygen demand (COD) of 14,843 ± 350 mg/L, reducing it to approximately 170 ± 12 mg/L over the operational period. This configuration facilitated a significant increase in cell volume utilization of 89.5%, and achieved a maximum current production of 18.03 mA, along with hydrogen generation of 24.34 ± 1.3 mL at a biomass concentration of 13.5 ± 1.1 g/L. Cell growth contributed substantially to the degradation of organic matter, with sludge consumption reaching 12 g/L. The system produced an output voltage of 1.88934 ± 0.0091 V within 72 h and achieved the highest power density of 261,037 ± 1,245 mA/m
