Effect of Adenotonsillectomy on Spectral and Acoustic Characteristics.
Article in Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Acoustic analysis and perceptual analysis has been extensively used to assess the speech and voice among individual with voice disorders. These methods provide objective, quantitative and precise information on the speech and voice characteristics in any given disorder and help in monitoring any recovery, deterioration, or improvement in an individual's speech and also differentiate between normal and abnormal speech and voice characteristics. The present study was carried out to investigate the spectral characteristics (formant frequency parameters and formant centralization ratios) and voice characteristics (Acoustic parameters of voice) changes in individuals following adenotonsillectomy. A total of 34 participants participated in the study with a history of adenotonsillar hypertrophy. Spectral and acoustic voice parameters were analyzed across the three-time domains, before surgery (T0), 30 days (T1), and 90 days (T2) after surgery. Data was analyzed statistically using the SPSS software version-28.0.0.0. Descriptive statistics were used to find the mean and standard deviation. Repeated measures of ANOVA were used to compare the pre and post-experimental measures for spectral and acoustic, voice parameters. The derived parameter of acoustic vowel space (formant centralization ratio 3) was compared across three conditions timelines. The results revealed that acoustic vowel space measure and formant frequency measures were significantly increased in pre and post-operative conditions across the three timelines. A significant difference was obtained across the acoustic parameters across the time domains. Adenotonsillectomy has been proved to be an efficient surgical procedure in treating children with chronic adenotonsillitis. The results obtained have indicated an overall improvement in the spectral and acoustic voice parameters thereby highlighting the need for adenotonsillectomy at the right time and at the right age.
