Aerodynamic measurements in singers at usual, low, and high frequencies.
Observational study in CoDAS, 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
purposeTo analyze aerodynamic measurements at habitual, low, and high frequencies in male and female singers without vocal changes.
methodsThis is a cross-sectional, analytical, observational study with 30 male and 30 female singers, aged 19 to 48 years. Aerodynamic parameters such as air pressure, expired and voiced airflow, expiratory volume, power and aerodynamic resistance, acoustic impedance, and aerodynamic efficiency were measured by emitting the syllable /pá/ seven consecutive times at usual intensity and usual, low, and high frequencies.
resultsModifications in aerodynamic measurements during the emission of different vocal frequencies were more evident in male singers. They had higher values of peak air pressure, aerodynamic resistance, acoustic impedance, and aerodynamic efficiency in high-pitched emissions, while female singers had higher values of aerodynamic efficiency in usual emissions, followed by high-pitched emissions.
conclusionThe variation in fundamental frequency of the voice causes greater changes in aerodynamic parameters in male singers. Female singers had higher values of aerodynamic efficiency in usual voice production.
