Spss statistical software program

Statistical analyses were performed using the SPSS statistical software program, version 25.0 (IBM Corporation, Armonk, NY, USA). Categorical data were presented as proportions or percentages (%), and comparisons between groups were analyzed using the χ² test with a significance level of α = 0.05, considering P < 0.05 as statistically significant differences. Continuous variables were expressed as median and interquartile range, as normality tested by using normal probability cumulative distribution chart method, was not met. Comparison between groups was thus performed using Mann-Whitney U-test.

Data analyses were performed with use of the IBM SPSS Statistical Software program (version 19). All hypotheses were tested at a significance level of 0.05. χ² tests or Fisher exact tests were used for categorical variables. Mann-Whitney U-tests were used to compare independent groups on continuous variables lacking a normal distribution. Subgroup analyses were performed for Shandong and Zhejiang parents.
Parental COVID-19 vaccine hesitancy was used as a dependent variable, while independent variables were: age, sex, marital status, working status, occupational classification, education level, number of hours worked per day, residence, yearly household income, number of children raised, history of children's COVID-19 infection, vaccination in the past 3 years, adverse effects of any vaccinations, a history of COVID-19 infection in family members, attendance at COVID-19 vaccination lectures, SSRS (i.e., objective, subjective, or utilization of support) and PACV domains (behavior, safety and efficacy, and general attitudes). There is no linear relationship between parental vaccine hesitancy and the independent variables. Multivariate logistic regression analyses were performed using stepwise variable selection with all variables entered into the model to evaluate the independent influence of COVID-19 vaccine hesitancy among Shandong and Zhejiang parents.

The data of the present study were analyzed using the SPSS statistical software program (version 18.0, IBM, Chicago, IL, USA).

MetaMorph software (v. 6.0; Molecular Devices, Boston, MA, USA) was used to analyze the cell image data. Average background signal was determined as the mean fluorescence intensity from a blank area and was subtracted from the raw image before carrying out FRET calculations. The mean intensity of a ROI of the corrected FRET image was measured. Western blotting results were normalized with GAPDH. The mean and standard deviation were used to express protein levels of ROCK, p-ROCK, cofilin-2, p-cofilin-2, LIMK, and p-LIMK1. Statistical analyses were performed using the SPSS statistical software program (v. 17.0; IBM, Chicago, IL, USA). Data were expressed as means ± S.E.M. Independent experiments were performed thrice. Statistical analysis was performed with student’s t-test. p values less than 0.05 were considered statistically significant.

The online survey was created using the SurveyXact online survey platform.² A report and data set were exported from the SurveyXact to SPSS statistical software program (IBM Corp, 2020 ). We started with the preliminary analysis and examining the intercorrelations between all study variables. The study relied on the item-total score correlations in evaluating individual responses to the HSCL-25, based on the full 25 items instead of subscales (Lhewa et al., 2007 (link); Lee et al., 2008 (link); Vindbjerg et al., 2021 (link)). Next, hierarchical regression analysis was conducted to examine the ability of the different integration variables in predicting psychological distress (measured by HSCL), after controlling for age and education. Due to the lack of significance, gender was not included in the regression analysis. Scores on psychological, social, and linguistic integration and the single items of the navigational and economic scales were included as predictors in the analysis. We also calculated 95% confidence intervals for the regression coefficients based on robust standard errors (see Table 2).

To evaluate intrarater agreement, two identical images were printed and mounted in the album together with the other photographs. The evaluators’ scores for these duplicate photographs were analyzed using the Intraclass Correlation Coefficient (ICC).
To analyze the measurement reproducibility, the scales of 30 evaluators were re-measured after an interval of four weeks. A paired t test was applied with the purpose of evaluating the significance of the differences between the two measurements, thus demonstrating the systematic error. The Dahlberg formula (Se²= ∑d²/2n) was used to evaluate the casual error.
Descriptive statistics were reported as means and standard deviations. The measurements were submitted to the Kolmogorov-Smirnov test to evaluate the data distribution. To evaluate laypersons’ aesthetic perceptions of metal archwires with and without aesthetic coating, the one-way analysis of variance (ANOVA) with the Tukey post-hoc test were applied. These tests were also used to compare the three age groups. To evaluate the archwires’ aesthetic perception between genders, the Mann-Whitney test was applied. The level of significance was established at 5%. All analyses were performed with the SPSS statistical software program (version 21.0, IBM Corporation, Armonk, New York, USA).
