[…] SPSS ver. 18.0 for Windows software (SPSS Inc., Chicago, IL, USA) was used for statistical analysis in this study. The clinical characteristics and VFSS scores of the patients with Parkinson disease were analyzed with a nonparametric testing method using the Mann-Whitney U test. Patients were divided into two groups, one with aspiration pneumonia and one without aspiration pneumonia. Multiple logistic regressions were performed to control the gender, age, and other statistically significant variables to exclude the effects of factors that might have influenced the occurrence of aspiration pneumonia among the patients with Parkinson disease. A p-value of less than 0.05 was considered significant.To calculate the sample size for logistic regression analysis, we used G*Power for Windows (ver. 3.1.9) with an effect size of 0.5, an alpha risk of 0.05, and a power of 0.80. The resulting calculated sample size was 53 patients. Considering a 10% dropout rate, the corrected sample size was 59 patients. […]
