Statistical analysis was performed with SPSS statistical program version 13.0 (SPSS, Chicago, IL, USA). Differences in the distribution of MTHFR genotypes as well as methylation status among patients and controls were examined by using the χ2 test or Fisher’s exact test, where appropriate. A value of p < 0.05 was considered statistically significant.

All statistical analyses were performed using SPSS Statistical Program, version 13.0 (SPSS, Inc, Chicago, IL). Chi-square tests were used to compare the glove perforation in relation to different baseline characteristics. The relative risk between the operative participants was also analyzed. Independent risk factors influencing surgical glove perforation were determined by multiple logistic regression analysis. The P values <0.05 were considered statistically significant.

The intra- and interobserver reliability was tested using the intraclass coefficient (ICC) test using the 2-way mixed and absolute agreement model. The ICC values were classified as follows: 0.8 to 1.00 as strongly reliable, 0.6 to 0.79 as reliable, and ≤ 0.59 as unreliable.[13 (link)–15 ] The differences between the levels were analyzed by Wilcoxon signed-rank test. The entry point of the axial plane was analyzed as percentage of the axial width of the SAP; statistical significance of the differences was analyzed by Wilcoxon signed-rank test for the upper, middle and lower thoracic levels. The sagittal safety margin for the entry point related to the fixed-angled trajectory was analyzed by one-sample t-test. All statistical analyses were performed using SPSS Statistical Program, version 13.0 (SPSS, Inc, Chicago, IL). P < .05 was considered significant.

The allele and genotype frequencies were estimated by counting. The agreement of genotype frequencies with the Hardy-Weinberg equilibrium expectations was tested using the chi-square test. The SPSS statistical program version 13 was used to compare categorical variables among groups and adjusted residuals. Comparisons of mean values of quantitative variables were carried out by independent t-tests and ANOVA by ranks with Tukey’s post hoc test correction for multiple comparisons. Significance was considered at P < 0.05.

All data are expressed as mean ± standard deviation. Differences between the control and the experimental groups were analyzed using a 2-tailed Student t test. One-way analysis of variance was used for multiple group comparisons. Statistical analysis was performed using the SPSS statistical program version 13 (SPSS Inc., Chicago, IL, USA). Differences with P < 0.05 (*), P < 0.01 (**), or P < 0.001 (***) were considered statistically significant.

Statistical analysis was performed using the SPSS statistical program version 13 (SPSS Inc. Chicago, IL). All the experiments were carried out at least in triplicate. The results were expressed as means ± SD. Differences between the two groups were analyzed by the two-tailed Students t-test. Differences of P < 0.05 (*), P < 0.01 (**) or P < 0.001 (***) was indicated.

Experiments were carried out at least in triplicate and results were expressed as mean ± SD. Statistical analysis was performed using SPSS statistical program version 13 (SPSS Inc., Chicago, IL). Difference between two groups was analyzed by two-tailed Student's t test and that between three or more groups was analyzed by one-way ANOVA multiple comparisons. Difference with p < 0.05 (*) or p < 0.01 (**) was 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.
