Unique mating behaviours in knife livebearers of the genus Alfaro (Poeciliidae): New observations from Alfaro huberi.
Article in Journal of fish biology, 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
Poeciliid fishes show diverse courtship displays. Building on recent work in Alfaro cultratus, we document mating behaviours in its only congener, Alfaro huberi. In both species, males adopt a unique posture above females and initiate physical contact. A. cultratus males rub the tops of females' heads with their pelvic fins, whereas A. huberi males touch females' chins with the gonopodium, a modified anal fin used in copulation. We compare these behaviours and discuss how differences may relate to the distribution of female sensory organs.
