Effect of Treatment of Hypokinetic Dysarthria in Parkinson's Disease with Speech and Language Therapy: A Meta-Analysis.
Review in Iranian journal of public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: A meta-analysis study was conducted to measure how to forecast the effect of treatment of hypokinetic dysarthria in Parkinson's-disease with speech and language therapy. Methods: Until October 2024, a comprehensive literature research was conducted, and 1665 related studies were reviewed. The 14 selected studies encompassed 948 participants with hypokinetic dysarthria in Parkinson's disease. The odds ratio (OR) mean difference (MD) and 95% confidence intervals (CIs) were used to look at the outcome of treatment of hypokinetic dysarthria in Parkinson's disease with speech and language therapy using dichotomous or continuous methods with a fixed- or random-effects model. Results: In individuals with hypokinetic dysarthria in Parkinson-disease, speech and language therapy had significantly higher sound pressure level, phonation (MD, 7. 51; 95% CI, 3. 81-11. 20, p<0. 001), reading (MD, 8. 83; 95% CI, 4. 96-12. 69, p<0. 001), monologue (MD, 4. 28; 95% CI, 2. 47-6. 10, p<0. 001), and picture description (MD, 3. 64; 95% CI, 1. 78-5. 50, p<0. 001), and lower Voice Handicap Index (MD, -5. 61; 95% CI, -9. 05- -2. 17, p=0. 001) compared to control treatment. Conclusion: In individuals with hypokinetic dysarthria in Parkinson's disease, speech and language therapy had significantly higher sound pressure level, phonation, reading, monologue, and picture description, and lower Voice Handicap Index compared to control treatment. To validate these finding more studies are required, caution is needed when interpreting these results, since many comparisons had a limited number of selected studies.
