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

The sesquiterpene α-humulene (alpha-humulene, humulene, or HUM) is recognized for its anti-inflammatory actions. However, its pharmacological potential in the central nervous system (CNS) remains largely unexplored. In this study, we evaluated the acute toxicity and behavioral responses of adult zebrafish (Danio rerio) to intraperitoneal (IP) injection of HUM. The behavioral parameters examined were number of line crossings (open-field test) and time spent in the light zone of the tank (light/dark test). Then were performed experiments with standard antagonists to investigate the possible mechanism of action. Humulene exhibited low acute toxicity (LD
