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
purposeVocal fold motion impairment (VFMI) has been reported as a complication of stroke worldwide. However, the incidence and risk factors are unknown. This study aimed to assess the incidence and associated risk factors of post-stroke VFMI.
methodsA query of the 2016-2023 New York State SPARCS database was performed using ICD-10 codes for adult patients with cerebral infarction (I63.x), intracerebral hemorrhage (I61.x), or subarachnoid hemorrhage (I60.x). Chi-square with post-hoc column proportion testing was performed for univariate analysis of patient demographics and comorbidities. Multivariable logistic regression analysis was used to determine odd ratios of developing VFMI after stroke controlling for patient demographics and comorbidities.
resultsA total of 417,149 stroke patients were isolated. The number of patients diagnosed with VFMI after stroke was 1,473 (0.4%). Times to diagnosis of VFMI were within admission for stroke, 674 (45.9%); within 1 year, 457 (31.1%); between 1 and 2 years, 146 (9.9%); and more than 2 years: 192 (13.1%). Unilateral VFMI was most common, with 969 patients (65.8%), followed by unspecified VFMI, with 315 patients (21.4%), and lastly bilateral VFMI with 189 patients (12.8%). Multivariate analysis showed that VFMI patients have an increased odds ratio having chronic pulmonary disease (OR 1.32; p < 0.001) and having coagulation disorders (OR 1.49; p < 0.001).
conclusionVFMI is a rare complication after stroke, affecting 0.4% of patients. More research is needed to understand the risk factors that place patients at a higher risk of VFMI following stroke and aid in early screening/intervention.
