To examine the influences of PV induced moving people on postural control in healthy adults, one-way repeated analysis of variance was used. As a post hoc test, the Bonferroni correction was utilized, and the significance level was set at α=0.05. The collected data were analysed using IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA).

Categorical data were analyzed by chi-square tests, and t-tests were used for interval/ordinal data. Functional primary patency and AVF survival, stratified by the assessment method (physical examination alone or duplex ultrasound), were plotted using the Kaplan-Meier method, with patient follow-up censored for death, renal transplant, or transfer to a nonparticipating dialysis unit. The Cox multivariate proportional hazards regression model was used to identify independent predictors of clinical outcomes. All statistical analyses were performed using IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA), with P-values ≤ 0.05 considered statistically significant.

IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA) and R ver. 2.15.2 (R Foundation for Statistical Computing, Vienna, Austria; http://www.r-project.org/) were used for statistical analyses. Chi-square test and Student t-test for independent samples were used for comparisons between the radiography and endoscopy groups. For all data analyses, P < 0.05 was considered statistically significant.

Pearson chi-square test for categorical variables and linear-by-linear association method for continuous variables were employed in univariate analyses to evaluate the association of multiple clinical parameters between the ERCP group and control group. Multiple regression analysis was performed to examine for correlation between clinical parameters and postoperative ERCP. IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA) was employed for statistical analyses. A probability value below 0.05 was regarded as statistically significant.

The sample size was determined on the basis of published data regarding the efficacy of tube insertion in reducing the prevalence of middle ear effusion in children with chronic OME [12 (link)]. Assuming that there would be no patients lost to follow-up and a standard deviation of 0.20, it was calculated that 60 subjects in each group would lead to a beta error margin of 0.20, an alpha value of 0.05, and a power of 80%.
The results are given as arithmetical mean values±standard deviation. Age distribution and percentage choanal obstruction due to adenoidal hypertrophy before and after surgery were tested using the Mann-Whitney nonparametric test, and Fisher exact probability test was used to analyse the between-group differences in the tympanometric, audiometric and otoscopic findings.
The statistical analyses were made using the IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA); a P-value of <0.05 was considered statistically significant.

In this study, we analyzed the data by using the IBM SPSS ver. 18.0 (IBM Co., Armonk, NY, USA). Specifically, we conducted paired t-tests to compare performance between pretests and posttest, and to verify the effectiveness of the cognitive enhancement gymnastics program for the elderly with dementia.
