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 African seahorse Hippocampus algiricus has been considered restricted to the eastern Atlantic coast of Africa, with occasional records in Macaronesian archipelagos. The species is currently classified as Vulnerable by the International Union for Conservation of Nature (IUCN). Here, we report the first confirmed occurrence of this species in the Mediterranean Sea, based on photographic and video evidence. The specimen was identified using diagnostic morphological characters and morphometric analysis. This record represents a north-eastern range extension and aligns with ongoing tropicalization processes in the western Mediterranean driven by rising sea temperatures.
