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

Animal welfare is increasingly assessed through the "Five Domains" framework, where monitoring brain activity via electroencephalography (EEG) is essential for objectively evaluating sleep-wake cycles and neurological health. However, traditional EEG studies in animals often require invasive procedures, anesthesia, and movement restriction, which compromise both animal welfare and natural behavior. To overcome these limitations, we developed a miniaturized wireless EEG device (24.8 × 24.8 × 8.2 mm; 5.2 g) with Bluetooth transmission, surface electrodes, and biocompatible adhesives. This system allows 10-12 h of recording without restricting movement while remaining compatible with animal welfare standards. We validated the methodology in three amniote species representing major vertebrate classes: Aldabra giant tortoise (
