Is voice therapy an effective treatment for dysphonia? A randomised controlled trial.
Trial report in BMJ (Clinical research ed.), 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02409758 (The Effectiveness of the Comprehensive Voice Rehabilitation Program Compared With Vocal Function Exercises Method in Behavioral Dysphonia), which is not on this map. Cited by 27 papers, 4 of them syntheses that pooled it.
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.

Abstract
objectivesTo assess the overall efficacy of voice therapy for dysphonia.
designSingle blind randomised controlled trial.
settingOutpatient clinic in a teaching hospital.
participants204 outpatients aged 17-87 with a primary symptom of persistent hoarseness for at least two months.
interventionsAfter baseline assessments, patients were randomised to six weeks of either voice therapy or no treatment. Assessments were repeated at six weeks on the 145 (71%) patients who continued to this stage and at 12-14 weeks on the 133 (65%) patients who completed the study. The assessments at the three time points for the 70 patients who completed treatment and the 63 patients in the group given no treatment were compared.
main outcome measuresRatings of laryngeal features, Buffalo voice profile, amplitude and pitch perturbation, voice profile questionnaire, hospital anxiety and depression scale, clinical interview schedule, SF-36.
resultsVoice therapy improved voice quality as assessed by rating by patients (P=0.001) and rating by observer (P<0.001). The treatment effects for these two outcomes were 4.1 (95% confidence interval 1.7 to 6.6) points and 0.82 (0.50 to 1.13) points. Amplitude perturbation showed improvement at six weeks (P=0.005) but not on completion of the study. Patients with dysphonia had appreciable psychological distress and lower quality of life than controls, but voice therapy had no significant impact on either of these variables.
conclusionVoice therapy is effective in improving voice quality as assessed by self rated and observer rated methods.
