Auditory brainstem responses in two closely related Peromyscus species (Peromyscus leucopus and Peromyscus maniculatus).
Article in The Journal of the Acoustical Society of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 genus Peromyscus has been extensively used as a model for ecological, behavioral, and evolutionary studies. This study used auditory brainstem responses (ABRs), craniofacial morphology, and pinna measurements to compare two wild-caught species, Peromyscus leucopus and Peromyscus maniculatus. It was observed that P. leucopus exhibited larger features and bigger overall size compared to P. maniculatus. ABR recordings showed similar hearing thresholds with peak sensitivity between 8 and 46 kHz for both species. There were no significant differences between species for absolute amplitudes of waves IV and I, with significantly higher amplitude ratio of wave IV to wave I in P. leucopus across intensities. There were also species differences (faster wave I in P. maniculatus) and sex differences (faster wave I in female P. leucopus) for absolute latency, which were no longer significant when considering inter-peak latency between waves I and IV. Finally, faster normalized latencies of the binaural interaction component (BIC) were observed in P. maniculatus, while no differences were observed across relative BIC amplitude between species. These results provide additional ABR related data that expand the use of both Peromyscus species as future models for auditory research.
