Variations in advertisement call modulations do not influence vocal interactions in bullfrog choruses.
Article in JASA express letters, 2022. 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
Chorusing male bullfrogs naturally vary the number of modulations within their advertisement call notes. A field playback experiment investigated whether these variations affect males' evoked vocal responses. Vocal responses were quantified manually and automatically by quantifying acoustic energy. The numbers of calls, number of notes, latency of response, and detected-note acoustic energy did not vary significantly across playback stimuli for focal males or the entire chorus, suggesting that variations in modulation number do not carry relevant information to males. Future work can determine whether modulation cues may function in sexual selection and affect female response.
