Follow-up of patients with mild COVID-19 using subjective, acoustic, and aerodynamic measurements.

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
Objectives: To gain a comprehensive understanding of the vocal repercussions experienced by mild COVID-19 infection, as well as the duration and underlying factors contributing to these effects. Methods: Ten participants with mild COVID-19 infection were included as the experimental group to evaluate the voice metrics changes at 15 days (D15), 30 days (D30), and 60 days (D60) after mild COVID-19 infection, and 10 healthy people were taken as the normal control group. Self-assessment and objective measures were taken at each time point, including questionnaires for voice handicap index (VHI) and reflux symptom index (RSI), as well as acoustic and aerodynamic indicators such as fundamental frequency (F0), Jitter, Shimmer, noise-to-harmonics ratio, sound pressure level (SPL), phonation threshold pressure (PTP), phonation threshold flow, aerodynamic resistance(AR), aerodynamic efficiency, mean expiration airflow, maximum phonation time, and maximum loudest phonation time. Results: Notable elevations in RSI and VHI were observed during the D15 assessment, but by D60, these levels had returned to normal. At D60, Shimmer, PTP, and PTF significantly increased compared to the control group, while HNR and AR significantly decreased ( Conclusions: Our study demonstrated that COVID-19 infection has a detrimental effect on voice production. Although subjective discomfort may gradually subside within 2 months after onset, alterations in phonation mode can be delayed. It is essential for healthcare professionals to remain vigilant in preventing any organic changes that may arise due to COVID-19-related voice disorders, such as muscle tension dysphonia.
