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

Microbial fuel cells (MFCs) have been proven to be a green technology for solving energy crises, but their low power density limits their large-scale practical applications. In this paper, a three-dimensional porous composite hydrogel polyvinyl alcohol/polypyrrole (PVA/PPy) with good biocompatibility was prepared by temperature-field regulation via alternating cycles between low temperature (- 20 °C) and room temperature (25 °C) and used as the anode in MFC. The three-dimensional network structure of PPy nanospheres compressed by ice crystal stress exhibited excellent charge conduction capability and ion transport performance, which significantly improved the interfacial charge transfer efficiency of PVA/PPy-5 bioanode. Besides, the addition of PVA endowed the hydrogel with mechanical properties to resist the external forces. As the results, the maximum power density of PVA/PPy-5 MFC was 1521.04 mW/m
