Spss 22.0 windows

Baseline demographic characteristics and Retcam photographs of serial fundal examinations were evaluated. The proportion of eyes with ROP regression, additional treatment, and unfavorable anatomy were compared between the two groups 6 months after primary treatment as an endpoint. Statistical analyses were performed using SPSS 22.0 Windows (SPSS, Inc., Chicago, IL, USA). A p value of < 0.05 (2-sided) was considered significant for all tests. Data are presented as mean ± SD for continuous variables or as frequency (percentage) for categorical variables. Between-group differences were assessed using Chi-squared test or Fisher’s exact test for categorical variables, and Student t-test or Mann–Whitney test on ranks for continuous variables depending on the distribution. All p-values are two-tailed and considered significant if < 0.05.

The incidence of POD in a comparable patient population of a previous study was 28% (Robinson et al., 2009 (link)). Therefore, we assumed that the incidence of delirium would be reduced by one third in the DEX group in this trial. With significance set at 0.05 and power set at 80%, the sample size required to detect differences was 196, calculated with the Pass 11.0 software (NCSS, LLC. Kaysville, Utah, USA). Taking into account a lost-to-follow-up rate of about 6%, we planned to enroll 208 patients.
Continuous data with a normal distribution were presented as means ± standard deviation (SD) and analyzed using the independent t-test; those with a non-normal distribution were presented as medians (interquartile range) and analyzed by the Mann-Whitney U-test. Categorical variables were presented as frequencies and percentages and analyzed with the chi-square test or Fisher’s exact test. Repeated measurement analysis of variance was used to analyze the levels of pro-inflammatory markers. Statistical analyses were done on SPSS 22.0 Windows (IBM Corp., Armonk, NY, USA) with two-tailed tests wherever appropriate and P < 0.05 being considered statistically significant.

Continuous data with a normal distribution pattern would be presented as mean ± standard deviation (SD) and analyzed using the one-way ANOVA, and LSD-t-tests would be used for multiple comparisons. Data with a non-normal distribution pattern would be presented as median (interquartile range) and analyzed using the Kruskal–Wallis H test; Nemeyi tests would be applied for multiple comparisons. For the ordinal data, we would use the Kruskal–Wallis H test to assess the difference between the four groups; and Nemeyi tests would be used for multiple comparisons. Categorical variables would be expressed as frequencies and percentages and analyzed with the chi-square test or the Fisher's exact test. We would use the Cox's proportional hazard model to examine the survival status of the subchondral femoral head collapse between the four groups. Repeated measurement ANOVA would be used to analyze the repeated measurement data, such as VAS scores and HHS. Statistical analyses would be done according to the intention-to-treat principle on SPSS 22.0 Windows (IBM Corp, USA) with two-tailed tests wherever appropriate, and P < .05 would be regarded as statistically significant.

All data entry and analysis were carried out using SPSS Windows 22.0. Pearson’s correlations were run between traditional paper and pencil variables and CompCog variables. The p-values under 0.05 were considered to show statistical significance. A principal component analysis (PCA) with oblimin rotation (delta=0) was conducted on all items regarding time measures. ­Components were extracted based on eigenvalues of more than 1. Since the size sample was small, we used the Kaiser-Meyer-Olkin (KMO) measure to verify the sampling adequacy for the analysis. KMO was 0.662, above the level of 0.5 for adequacy. Bartlett’s test of sphericity (χ² (300)=1658.970, p<0.001) indicated that correlations between items were sufficiently large for PCA.

Children who underwent PT under elective general anesthesia in the pediatric and otorhinolaryngology clinic and pediatric intensive care unit between January 2007 and February 2017 were included in the study. The demographic characteristics of the patients, their ages, genders and indications were obtained from the files. Other information collected included indications, intubation time (0-21 days and more than 21 days), the experience of the surgeon (0-5 years and more than 5 years), surgical time (less than 30 minutes and more than 30 minutes) and surgical preferences (skin incision and tracheal incision) were compared to early and late complications.
For the statistical analysis, SPSS (Windows 22.0) was used. The Kruskal Wallis test was used for the evaluation of the relationship between the independent variables of the study and early or late complications. The findings were evaluated with a 95% confidence interval and a significance was assessed as p<0.05. The scientific ethics committee approval was taken from University of Health Sciences, Training and Research Hospital, prior to the study.
