Statistical methods: testing the normal distribution of variables in each group, non-normal distribution of information through the analysis, after logarithmic transformation. Was used to compare the various factors between the two groups chi-square test. Difficult to obtain device-related factors, using multiple Ordered Logistic regression analysis. Statistical analysis using the Statistical Package for SPSS11.5.
Statistical methods: Test the normal distribution variables in each group,analyze the data of non-normal distribution after the logarithmic transformation. Use chi-square test to compare the various factors between the two groups.Relevent factors of difficulty to obtain device can be applied to multiple Ordered Logistic regression analysis. Use the Statistical Package SPSS11.5 to do statistical analysis. 手工翻译····
