Influence of smoking isolated and associated to multifactorial aspects in vocal acoustic parameters.
Article in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionSmoking affect voice quality in a long period of time, but other factors may compromise it, such as professional using of voice, habits, alcohol dependence and GERD. The aim was associate the influence of these factors on vocal parameters. STUDY
designContemporary cohort study with cross-sectional. MATERIALS AND
methodsEighty adults of 35 to 60 years old had participated in this study, they had been divided into two groups, smokers (GF) and control (GC). There was application of questionnaire and voices were recorded. Praat software has been used for voice assessment and Man-Whitney, chi-square and logistic regression has been used for statistical analysis.
resultsThe GF had a higher incidence of alcohol dependence, coughing, throat clearing and professional voice using. Respecting to the acoustic parameters: noise-to-harmonic ratio (NHR), jitter and shimmer, the GF presented higher values. Relating these data to the questionnaire, it's noticed that female gender have influence over all acoustic parameters, GERD have influence over jitter and smoking can affect fundamental frequency, jitter, shimmer and NHR.
conclusionSmoking interferes in acoustics parameters isolated and associated with alcohol dependence, GERD, cough, throat clearing, gender and professional using of voice.
