Evidence for multiple past introgressions among chimpanzee subspecies during warming periods.
Article in Communications biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The evolutionary history of common chimpanzee (Pan troglodytes) subspecies is complex, marked by several past introgression events whose dating and location are unknown and are at odds with the current strong geographic segregation of the subspecies. We reconstruct the historical biogeography of common chimpanzee subspecies. Our findings reveal that cranial morphology reflects genetic differentiation, with the western chimpanzee being the most derived lineage. This is consistent with its current geographic isolation, which we find was punctuated by periods of potential contact with the other subspecies. These moments coincide with warming periods creating increased tree cover across the geographic barrier, the Dahomey Gap, currently separating western chimpanzee from the other subspecies. This integrative framework of a climate-mediated dynamical biogeography provides unprecedented insights into the dynamics of chimpanzee evolution, demonstrating how past climatic fluctuations and vegetation changes profoundly shaped the present-day distribution of Pan troglodytes subspecies along with their genetic differences.
