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
backgroundOccupational dysphonia or work-related voice disorders are a common problem among school teachers. Voice-related absenteeism and treatment expenses, the societal costs in the US alone have been estimated to be 2.5 billion dollars annually. Worldwide, many studies have been conducted; however, in Ethiopia, no studies have investigated teachers' voice disorders; with the epidemiology and magnitude of voice problems among Ethiopian teachers still unknown.
objectivesThis study aimed to investigate prevalence and associated factors of work-related voice disorders among school teachers in Sekota town wag himra zone, Ethiopia.
methodCross-sectional survey was conducted on 586 school teachers who worked in public schools in Sekota town, wag himra zone from April 1 to May 30, 2021. The participants were chosen using a census. A pretested and self-administered Voice Handicap Index-10 (VHI-10) scale questionnaire was used to obtain information on voice disorder and associated factors. Epi-data 4.6 and SPSS version 25 were used for data entry and analysis respectively. Univariate and Multivariate logistic regression analysis was carried out to ascertain the association between dependent and independent variables. 95% confidence interval (CI) was used to identify the factors significantly associated with voice disorder at a p-value ≤ 0.05.
resultsA total of 586 respondents were participated at a response rate of 92.1%. Most of 54.9%, 322/586) of the participants were males. The prevalence of work-related voice disorder among school teachers in the past 12 months was 21% (95% CI, (17.8-24.5), while that in primary school teachers was 24.8%, secondary school teachers was 19.3%, teachers college was 15.7% and Technical and Vocational Education and Training (TVET) was 11.5%. Infrequent nasal allergy [AOR:2.74,95% CI, (1.53-4.89)], having nasal allergy sometimes [AOR:5.38,95%CI, (2.10-13.77)], teaching consecutive 5th and 6th class [AOR: 5.64,95%CI(1.62-19.67)], speak over a natural breath cycle[AOR:3.94,95%CI, (1.3-11.90)], rarely drunk alcohol [AOR:6.28,95% CI (2.53-15.6)], sometimes drunk alcohol [AOR;3.27,95% CI (1.32-8.1), taking medications [AOR;9.52,95% CI, (1.82-49.86), stress and anxiety [AOR:2.32,95% CI, (1.04-5.15)], noise from children playing outside [AOR:3.1,95% CI, (1.45-6.43)] were found to be significantly associated factors with work-related voice disorders.
conclusionThis study concludes that work-related voice disorders are a common occupational hazard among school teachers. Provided most voice problems may be preventable and it can greatly affect their performance and quality of life interventions are paramount. Therefore, we recommend developing prevention programs including preventive voice training and voice hygiene with sanitary work conditions to combat functional voice disorder among school teachers.
