Advancing behavioural guidance systems to help conserve the European eel (Anguilla anguilla).
Article in Scientific reports, 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
This study investigated yellow (experiment 1) and silver-phase (experiment 2) European eel (Anguilla anguilla) behavioural response to pulsed direct current electric fields. Eel were offered a choice of two channels through which to pass under either: (1) a treatment condition, in which eel could select either an Electrified Channel (EC) or one in which the electric field was negligible (Non-Electrified Channel - NEC), or (2) a control in which the electric field was absent in both routes. In experiment 1, the influence of the EC field strength and direction of approach (upstream or downstream) on both initial and total channel passage and avoidance (reaction, route change and rejection) was assessed. In experiment 2, the influence of EC field strength and pulse frequency on initial channel passage and avoidance was investigated. The percentage of eel that passed the NEC under the treatment did not differ from the control in either experiment. In experiment 1, yellow-phase eel exhibited greater total avoidance in the EC when travelling upstream; but field strength had no effect. In experiment 2, silver-phase eel exhibited greater initial avoidance in the EC, but neither field strength nor frequency were influential. These findings will help optimise the design of devices that employ electric fields to guide eel.
