[Preliminary study of the temporal variables of continuous speech in patients with neurodegenerative syndromes of the frontotemporal lobar degeneration spectrum].

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
introductionNeurodegenerative diseases, especially frontotemporal lobar degeneration and Alzheimer's disease, often lead to impaired language functions, and so speech analysis can provide objective measures with which to classify the different syndromes.
aimTo study the nature, cognitive correlates and clinical utility of 21 variables related to speech and silence times. SUBJECTS AND
methodsDerivation of acoustic variables with Praat in three spontaneous speech tasks conducted in 22 subjects, distributed in six diagnostic groups (five with neurodegenerative diseases + control). A descriptive analysis is performed, with ROC and principal component curves, to study how acoustic variables are related to the different neurodegenerative syndromes and what information they can provide.
resultsThree groups of variables are identified related, respectively, to: a) total number of silent pauses and total duration of the task; b) variability of the phonic groups; and c) variability of the periods of silence. These components correlate differentially with the different syndromes studied.
conclusionsDetailed analysis of speech and silence times can provide relevant information for the diagnosis of different neurodegenerative syndromes that are not reflected in traditional neuropsychological assessments. Thus, the total number of silent pauses may be a valuable aid in discriminating patients with lexical access deficits, phonic group parameters seem to reflect motor speech problems, and pause variability is associated with dysexecutive and global impairment.
