Statistical package for social sciences program

Statistical analysis was performed using IBM's Statistical Package for Social Sciences program (SPSS, version 22.0, Chicago, IL, USA). Differences were considered statistically significant when p < 0.05.
In order to determine equality of variance and normal distribution, the Levene and Kolmogorov-Smirnov tests, respectively, were carried out. One-way ANOVA and Bonferroni's post hoc test were performed on the results with equality of variance and normal distribution. The nonparametric Mann–Whitney U test was performed on the data that did not have equality of variance and/or normal distribution.
Bivariate Pearson correlation was used to determine whether an association exists between intestinal IgA concentration and either relative abundance, absolute abundance, or the number of detected bacterial species.

Statistical analyses were carried out using Statistical Package for Social Sciences program version 23.0 Inc. Chicago, IL, USA. All variables were categorical and descriptive statistics for categorical variables were given as numbers (n) and percentages. Statistical analysis was performed to compare typical and atypical tomography findings in ambulatory and inpatient patients. Categorical variables were compared using Pearson’s Chi-squared test or Fisher’s exact test. Significance level was considered p<0.05.

Statistical analysis was performed using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA, version 20 for Windows). Descriptive data were analyzed using frequency and percentage and crosstabulation, and the Chi-square test was used to identify differences between groups, with a significance level of 5% (p < 0.05).

Descriptive data analysis was performed to analyze the demographic/clinical variables and HRQoL in haemophilia patients. Of the data collected, continuous data were presented as basic statistics (number of observations, averages, and standard deviations) and categorical variables were presented as frequency and percentage (%). HRQoL was compared according to the demographic and clinical variables. The Student’s t-test and Mann–Whitney U test were used to examine differences according to the normality of distribution for the variable. For multiple comparisons, the Bonferroni correction was utilized. To assess whether the generic and disease-specific instruments agree, the Pearson’s correlation coefficients were calculated. Multiple linear regression analyses were performed to determine the clinical factors associated with HRQoL using backward elimination. All final significance levels reported were two-tailed, and statistical significance was estimated at p ≤0.05. The Statistical Package for Social Sciences program (version 20.0) was used for statistical analysis.

Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA) version 16 was used for data entry and for analysis of the patients demographic characteristics; clinical diagnosis and findings of H. pylori infection were analyzed by simple descriptive statistics. Chi-square test was used to compare every two variables. A p value lower than 0.05 was statistically significant.

The Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA) was used for statistical analyses. To compare two means of unpaired data, the t-test was used. To compare 3 means of unpaired data, the data were compared using one-way analysis of variance (ANOVA) and the post hoc Tukey test (for a homogenous subset), or Dunnett’s T3 multiple-comparison test (for a non-homogenous subset). For data that were not normally distributed, nonparametric analyses (Kruskal-Wallis test) were used. A p value < 0.05 was considered statistically significant. All of the data are expressed as the means ± standard deviations (SD), except the median (range) for T_max.
