The existence of phonatory instability in multiple sclerosis: an acoustic and electroglottographic study.

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
Dysarthria and phonatory symptomatology are often reported by patients suffering from multiple sclerosis (MS), but have been poorly investigated, although related to life quality. The objective of the study was to investigate the phonatory function in MS patients using objective measures. The speech of 64 MS patients and 64 pair-matched controls was recorded and analyzed using electroglottography, a physiological method that measures the electrical conductance during the opening and closing phases of the vibrating vocal folds. Electroglottographic parameters were correlated with clinical and MRI features. Most of the variables that have been used for the analysis of voice (vocal jitter P = 0.041, standard deviation of the average fundamental frequency P = 0.018, and the mean fundamental frequency of the vibrating vocal folds P = 0.025) differentiated the MS group from the control group. Phonatory function is impaired in MS patients, and physiological methods, such as electroglottography, are useful tools to assess it.
