Comparative Analysis of ASD and Control

All demographic and clinical variables were subjected to statistical analysis. Descriptive analysis was conducted for sociodemographic variables featuring the two samples (ASD and control groups). To compare the gender between the ASD and control groups, we used the Fisher’s exact test. Student’s t-test was used to examine the differences in age, NAA/Cr (mean value), and Cho/Cr (mean value) between the ASD and control groups. In addition, the Student’s t-test was also used to examine the differences in NAA/Cr (mean value) and Cho/Cr (mean value) between children with ASD and children with ASD and cognitive impairment. Statistical significance was considered for a P-value ≤0.05. We used the statistical program Statistical Package for Social Science 20.0.

Mean and standard deviation were determined for each variable studied. Statistical significance was evaluated using one-way analysis of variance (ANOVA) followed by Bonferroni post hoc test for multiple comparisons. For bivariate analysis, Spearman’s correlation coefficient was calculated. All the analyses were performed using Statistical Package for Social Science 20.0 (SPSS, Chicago, IL, USA).

Results of the analysis were subjected to one-way analysis of variance (ANOVA) and multiple comparisons of means by post hoc Tukey’s procedure by Statistical Package for Social Science 20.0 software (International Business Machines Corporation). The dissimilarity index was calculated using Darwin (6.0.15) software package. Multivariate statistical analyses were carried out using XLSTAT 2018 software (Addinsoft) for Microsoft Excel®.

Epidemiological Study of Infective Endocarditis

The data were stored in Microsoft Access 2010 and were analyzed using Statistical Package for Social Science 20.0 (IBMcorp, Chicago, IL, USA). Categorical variables are presented as percentages and were compared using the chi-squared or Fisher's exact tests as appropriate. Continuous variables are summarized as medians and interquartile ranges, and the Mann–Whitney U test was used to evaluate the group differences. Odds ratios (OR) with 95% confidence interval (CI) were calculated using logistic regression. The variables of interest included the epidemiological data, predisposing factors, place of IE acquisition, laboratory tests, and echocardiographic findings as well as the causative pathogens. After univariate analysis, variables with P values less than 0.05 were included in forward stepwise logistic regression to identify independent variables. The site of IE acquisition was included in the regression model as coded dummy variables. P values less than 0.05 were considered statistically significant.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
