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

Electroactive biofilms (EABs) hold significant potential for applications in bioenergy, biosensing and wastewater treatment; however, their performance is frequently hindered by inefficient extracellular electron transfer (EET). A notable example of this limitation is the significant impact of low EET efficiency on the sensitivity of EAB-based biosensors. To address this, we engineered Geobacter sulfurreducens anode biofilms by enhancing intracellular levels of cyclic GMP-AMP (cGAMP) through the overexpression of cGAMP synthase. This approach resulted in the formation of thin yet highly conductive biofilms. When utilized in a microbial fuel cell biosensor, the engineered biofilm demonstrated a 20-fold improvement in detection limit for Cd(II), achieving 0.03 mg L
